\section{Introduction}
- This package started as a personal package a few years ago that I used in various projects. Firstly, it was written in \tex{} and \latex, which gave rise to various errors as the complexity of the package grew larger and ended up as a spaghetti code. Therefore, the code was rewritten into the \latex3 language and may now be easily maintained. Originally this package was written because there did not exist any great package for derivatives. It was first much later that I discovered the \pkg{diffcoeff} package, which does a good job. However, at this time, I had already written much of the code with no documentation. So I decided to write one and make it into a package for the public.
-
- As a note on terminology, I use the wording \emph{infinitesimal} abbreviated as \texttt{inf} for the operator symbols $d, \partial, \delta$ etc. that used in derivatives like $\odv{y}{x}, \pdv{y}{x}, \fdv{y}{x}$ and in differentials like $\odif{x}, \pdif{x}, \fdif{x}$. In the description of macros and options, I often write \emph{cs-\meta{placeholder}} to denote a comma-separated list of \meta{placeholder}. For example, \oarg{cs-numbers} is used in the option section for math space keys to denote comma-separated list of numbers. It should also be noted that whenever an argument reads \meta{keyvalue list}, it means that it is a comma-separated list of keyvalue pairs.

- \section{Derivative}
-
- \begin{function}*{\pdv}
- \begin{syntax}
- \sarg, \oarg{keyval list}, \marg{function}, \targ{/}, \marg{variables}, \earg{\_, point\tsb{1}, \^, point\tsb{2}}
- \end{syntax}
- The partial derivative \macro{1} is defined with a set of mandatory and optional arguments that either typeset specific parts or changing the style of the derivative. In this package, the partial derivative is defined with an italic partial differential $\partial$ as
-
- \begin{definition}
- \DeclareDerivative{\pdv}{\partial}[style-var=multiple, sep-inf-ord=1,
- delims-eval=(), delims-eval-/=()]
- \end{definition}
-
- \begin{argument}*{1}
- The first argument of \macro{1} is an optional star that determines where the function is typeset; either in the numerator of the fraction or next to the fraction. Using the option \keyval{switch-*}{false}, the function is typeset in the numerator when the star is absent, and next to the fraction when the star is present as shown below
-
- \begin{example}
- \pdv{f}{x,y} \\
- \pdv*{f}{x,y}
- \end{example}
-
- \noindent The effect of the star's presence can be switched around using \keyval{switch-*}{true} i.e. the equations in the above example are exchanged.
- \end{argument}
-
- \begin{argument}{2}[updated = v1.0]
- The second argument is optional and is written inside square brackets. This argument is used to set the options of the derivative using a \keyval[index=false]{key}{value} semantic. For example the order of differentiation can be set via the \key[cat=misc]{order} option
-
- \begin{example}
- \pdv[order={2,3}]{f}{x,y} \\
- \pdv[order={\beta,a,n+2a}]{f}{x,y,z} \\
- \pdv[order={2,n^2,n^2-1}]{f}{x,y,z} \\
- \pdv[order={2,n^2}]{f}{x,y,z}
- \end{example}
-
- \noindent The list of options that can be applied to derivatives can be found in \cref{ssec:options_dv}.
-
- %The order may be a number, a symbol and a combination hereof. Note that the total order of differentiation (i.e $\odif[order=n+2]{}$) is automatically calculated and sorted. This is particularly useful when dealing with mixed partial derivatives which is further described in \cref{ssec:DV_pdv,ssec:overall_order}
- \end{argument}
-
- \begin{argument}{3}
- This is the first mandatory argument that typeset the function that is to be differentiated
-
- \begin{example}
- \pdv{f(x,y,z)}{x,y,z} \\
- \pdv{e^x\sin(y)\ln(z)}{x,y,z}
- \end{example}
-
- \noindent The function is simply typeset in the numerator or next to the fraction.
- \end{argument}
-
- \begin{argument}{4}
- The fourth argument is an optional slash written \emph{between the function and the variable} arguments and determines which fraction style the derivative is typeset with, as described in \cref{ssec:options_dv}. Using the option \keyval{switch-/}{false} and the package's default fractions, the derivative is typeset with \cs{frac} when the slash is absent, and \cs{slashfrac}\footnote{which is a macro defined by the package, see \cref{ssec:slashfrac} for more information.\label{foot:sfrac}} when the slash is present, as shown below
-
- \begin{example}
- \pdv{f}{x,y} \\
- \pdv{f}/{x,y}
- \end{example}
-
- \noindent As for the star argument, the effect of the slash's presence can be switched around using \keyval{switch-/}{true} i.e. the equations in the above example are exchanged.
- \end{argument}
-
- \begin{argument}{5}
- This is the second and final mandatory argument, which purpose is to typeset the variable in which the function is differentiated with respect to. The variables are given in a comma-separated list e.g. \texttt{\{x, y, z\}}
-
- \begin{example}
- \pdv{f}{x} \\
- \pdv{f}{x,y}
- \end{example}
-
- %\noindent The variable is always typeset in the denominator.
- \end{argument}
-
- \begin{argument}{6}
- This is the last optional argument that specifies the point(s) of evaluation or variables held constant. It is an \emph{e-type} argument in the \pkg{xparse} language and is given by \verb|e{_^}|. This means that the subscript \verb|_| and superscript \verb|^| accepts an argument given in braces. Moreover, the order of \verb|_| and \verb|^| is independent as shown below
-
- \begin{example}
- \pdv{f}{x,y}_{(x_1,y_1)} \\
- \pdv{f}{x,y}^{(x_2,y_2)} \\
- \pdv{f}{x,y}_{(x_1,y_1)}^{(x_2,y_2)} \\
- \pdv{f}{x,y}^{(x_2,y_2)}_{(x_1,y_1)}
- \end{example}
-
- \noindent The subscript argument is commonly used as the point of evaluation or variables held constant. If needed, the superscript argument may be used for the second point of evaluation.
- \end{argument}
-
- \end{function}
-
- \subsection{Other derivatives}
- This package offers five other derivatives: Ordinary derivative \macro{\odv}, material derivative \macro{\mdv}, functional derivative \macro{\fdv}, the average rate of change \macro{\adv} and the Jacobian \macro{\jdv}. A unique feature of this package, is that you can define your own derivatives as described in \cref{ssec:defvar_dv}.
-
- \begin{function}{\odv}[updated=v1.1]
- \begin{syntax}
- \sarg, \oarg{keyval list}, \marg{function}, \targ{/}, \marg{variables}, \earg{\_, point\tsb{1}, \^, point\tsb{2}}
- \end{syntax}
- In this package, the ordinary derivative is defined with an upright lowercase d if the package option \keyval{upright}{true} is used else it will use an italic lowercase d
- \begin{definition}
- \DeclareDerivative{\odv}{\mathrm{d}}%\marginnote{\keyval{upright}{true}}%
- \DeclareDerivative{\odv}{\mathnormal{d}}%\marginnote{\keyval{italic}{true}}%
- \end{definition}
- because it is used by many nowadays books
- \begin{equation*}
- \odv{f}{x} = \lim_{h\to 0} \mleft( \frac{ f(x+h) - f(x) }{ h } \mright)
- \end{equation*}
- However it can always be changed with the \key{style-inf} key.
- \end{function}
-
- \begin{function}{\mdv}[updated=v1.1]
- \begin{syntax}
- \sarg, \oarg{keyval list}, \marg{function}, \targ{/}, \marg{variables}, \earg{\_, point\tsb{1}, \^, point\tsb{2}}
- \end{syntax}
- The material derivative is used in some branches of physics e.g. thermodynamic, fluid dynamic etc. It comes with an upright uppercase D when the package option \keyval{upright}{true} else it will use an italic uppercase D. In this package, the material derivative is defined as
-
- \begin{definition}
- \DeclareDerivative{\mdv}{\mathrm{D}}%\marginnote{\keyval{upright}{true}}%
- \DeclareDerivative{\mdv}{\mathnormal{D}}%\marginnote{\keyval{italic}{true}}%
- \end{definition}
-
- \noindent In physics, the material derivative is defined by
- \begin{equation*}
- \mdv{ \varphi(\symbf{r}, t) }{ t } \coloneq \pdv{ \varphi(\symbf{r}, t) }{ t } + \dot{\symbf{r}} \cdot \nabla \varphi(\symbf{r}, t)
- \end{equation*}
- \end{function}
-
- \begin{function}{\fdv}
- \begin{syntax}
- \sarg, \oarg{keyval list}, \marg{function}, \targ{/}, \marg{variables}, \earg{\_, point\tsb{1}, \^, point\tsb{2}}
- \end{syntax}
- The functional derivative is used in the calculus of variation and uses a lowercase delta. With the package's default settings, it will use an italic delta. In this package, the functional derivative is defined as
-
- \begin{definition}
- \DeclareDerivative{\fdv}{\delta}
- \end{definition}
-
- \noindent In physics, it is for example used in the Lagrange equation or in the derivation of the Hartree-Fock equation
- \begin{equation*}
- \fdv{I}{q_{\alpha}} = \pdv{L}{q_{\alpha}} - \odv*{ \pdv{L}{ \dot{q}_{\alpha} } } { t } = 0, \qquad \fdv{ \symcal{L} }{ \psi_{n}^* } = \hat{F} \ket{\psi_{n}} - \epsilon_{n} \ket{\psi_{n}} = 0
- ,
- \end{equation*}
- respectively.
- \end{function}
-
- \begin{function}{\adv}
- \begin{syntax}
- \sarg, \oarg{keyval list}, \marg{function}, \targ{/}, \marg{variables}, \earg{\_, point\tsb{1}, \^, point\tsb{2}}
- \end{syntax}
- The average rate of change is defined to use an upright uppercase delta with the packages default settings. In this package, the average rate of change is defined as
-
- \begin{definition}
- \DeclareDerivative{\adv}{\Delta}
- \end{definition}
-
- \noindent The average rate of change is used to determine the slope of a straight line
- \begin{equation*}
- \adv{ y }{ x } = \frac{y_2- y_1}{x_2 - x_1}
- \end{equation*}
- \end{function}
-
- \begin{function}{\jdv}[updated = v1.0]
- \begin{syntax}
- \sarg, \oarg{keyval list}, \marg{function}, \targ{/}, \marg{variables}, \earg{\_, point\tsb{1}, \^, point\tsb{2}}
- \end{syntax}
- The Jacobian is defined to use an italic partial differential with the package's default settings. Also a pair of parentheses is automatically inserted around the function and variable. In this package, the Jacobian is defined as
-
- \begin{definition}
- \DeclareDerivative{\jdv}{\partial}[fun=true, var=1]
- \end{definition}
-
- \noindent which gives
- \begin{equation*}
- \jdv{f,g,h}{x,y,z}
- \end{equation*}
- \end{function}
-

- \section{Differentials}
-
- \begin{function}*{\odif}[new = v1.0, updated=v1.1]
- \begin{syntax}
- \sarg, \oarg{keyval list}, \marg{variables}
- \end{syntax}
- The differential \macro{1} is defined with a set of mandatory and optional arguments that either typeset specific parts or changing the style of the differential. It is defined with an upright lowercase d when \keyval{upright}{true} else it will be defined with an italic lowercase d
-
- \begin{definition}
- \DeclareDifferential{\odif}{\mathrm{d}}%\marginnote{\keyval{upright}{true}}%
- \DeclareDifferential{\odif}{\mathnormal{d}}%\marginnote{\keyval{italic}{true}}%
- \end{definition}
-
- \begin{argument}*{1}
- The first argument of \macro{1} is an optional star that determines the notation style of the differential. Using the option \keyval{switch-*}{false}, the variables and orders are typeset in a subscript and superscript respectively when the star is present. When the star is absent, then the macros associated infinitesimal is placed in front of each variable as shown below
-
- \begin{example}
- \odif{x,y,z} \\
- \odif*{x,y,z}
- \end{example}
-
- \noindent The effect of the star's presence can be switched around using \keyval{switch-*}{true} i.e. the equations in the above example are exchanged, as described in \cref{ssec:options_dv}.
- \end{argument}
-
- \begin{argument}{2}
- The second argument is optional and is written inside square brackets. This argument is used to set the options of the differential using a \keyval[index=false]{key}{value} semantic.
-
- \begin{example}
- \odif[order={n,3}]{x,y,z} \\
- \odif[sep-var-inf=0]{x,y,z} \\
- \odif*[sep-var-var=0]{x,y,z}
- \end{example}
-
- \noindent The list of options that can be applied to differential can be is found in \cref{ssec:options_inf}
- \end{argument}
-
- \begin{argument}{3}
- This is the mandatory argument, which purpose is to typeset the variables, as shown below
-
- \begin{example}
- \odif{x} \\
- \odif{s_1,s_2...,s_n}
- \end{example}
- \end{argument}
- \end{function}
-
- \subsection{Other differentials}
- This package offers four other differentials: partial differential \macro{\pdif}, uppercase D \macro{\mdif}, delta \macro{\fdif} and Delta \macro{\adif}. A unique feature of this package, is that you can define your own differential as described in \cref{ssec:defvar_inf}.
-
- \begin{function}{\pdif}
- \begin{syntax}
- \sarg, \oarg{keyval list}, \marg{variables}
- \end{syntax}
- The partial differential \macro{1} is typically used as a shorthand notation for the partial derivative. In this package it is defined as
-
- \begin{definition}
- \DeclareDifferential{\pdif}{\partial}[style-notation=single,
- style-notation-*=mixed]
- \end{definition}
-
- \noindent The non-star and star version gives
- \begin{align*}
- \pdif[order={i,j,k}]{x,y,z} &\coloneq \pdv[order={i,j,k}]{}{x,y,z} \\
- \pdif*[order={i,j,k}]{x,y,z} &\coloneq \pdv[order={i,j,k}]{}{x,y,z}
- \end{align*}
- respectively.
- \end{function}
-
- \begin{function}{\mdif}[updated=v1.1]
- \begin{syntax}
- \sarg, \oarg{keyval list}, \marg{variables}
- \end{syntax}
- Another commonly used shorthand notation for various derivatives is the differential with an uppercase D. In this package it is defined with a upright D when \keyval{upright}{true} else it is defined with an italic uppercase D
-
- \begin{definition}
- \DeclareDifferential{\mdif}{\mathrm{D}}[style-notation=single,
- style-notation-*=mixed]%\marginnote{\keyval{upright}{true}}%
- \DeclareDifferential{\mdif}{\mathnormal{D}}[style-notation=single,
- style-notation-*=mixed%\marginnote{\keyval{italic}{true}}%
- \end{definition}
-
- \noindent The non-star and star version gives
- \begin{align*}
- \mdif[order={i,j,k}]{x,y,z} \\
- \mdif*[order={i,j,k}]{x,y,z}
- \end{align*}
- respectively.
- \end{function}
-
- \begin{function}{\fdif}
- \begin{syntax}
- \sarg, \oarg{keyval list}, \marg{variables}
- \end{syntax}
- When working with functional derivatives another differential is frequently encountered. This differential uses a delta symbol and is defined as
-
- \begin{definition}
- \DeclareDifferential{\fdif}{\delta}
- \end{definition}
-
- \noindent For example an expression like
- \begin{align*}
- \fdif{J} = \int_{a}^{b} \pdv{L}{f} \fdif{f(x)} + \pdv{L}{f'} \odv*{ \fdif{f(x)} }{x} \odif{x}
- \end{align*}
- is frequently encountered.
- \end{function}
-
- \begin{function}{\adif}
- \begin{syntax}
- \sarg, \oarg{keyval list}, \marg{variables}
- \end{syntax}
- To wrap it up, a differential for differences is defined as
-
- \begin{definition}
- \DeclareDifferential{\adif}{\Delta}
- \end{definition}
-
- \noindent For example
- \begin{align*}
- \adif{E} = E_2 - E_1
- \end{align*}
- \end{function}
-
- \clearpage
- \section{Options}
-
- This package accepts its options using the well-known \emph{key=value} syntax. The keys are divided into categories, for which each key have its associated category as a prefix.
-
- \begin{function}{\derivset}[updated = v1.0]
- \begin{syntax}
- \marg{command}, \oarg{keyval list}
- \end{syntax}
- The \macro{1} is meant to set the default values for derivatives and differentials options in the preamble. It can be used in the document but this is what the new \oarg{keyval list} arguments are for in the derivative and differential commands.
-
- \begin{argument}{1}
- A mandatory argument that determines which command the \emph{key=value} pairs are assigned to, where the allowed \meta{commands} are the derivatives and differentials defined by the package and you, see \cref{ssec:defvar_dv,ssec:defvar_inf} for more information. The special value \texttt{all} is also allowed, which gives access to the options that applies to \textit{all} derivatives and differentials.
- \end{argument}
-
- \begin{argument}{2}
- This optional argument accepts its input as a comma-separated list of \emph{key=value} pairs. Leaving out \arg{2} sets the options to the package's default settings for the chosen \arg{1}. E.g. \macro{\derivset}[\narg{\macro{\odv}}] sets the options for the ordinary derivative to the packages default settings.
- \end{argument}
- \end{function}
-
- \subsection{Categories}
- This section seeks to give a detailed description of each category.
-
- \begin{itemize}
- \item The \key[index=false]{style-\meta{\dots}} keys sets either the font style or the fraction style of \meta{\dots}. The font styles \cs{mathnormal}/\cs{symnormal} and \cs{mathrm}/\cs{symup} are commonly used in literature. The fraction style can be either \cs{frac}, \cs{dfrac}, \cs{tfrac}, \cs{sfrac}\req{}, \cs{slashfrac}\footref{foot:sfrac} or any command with two mandatory arguments.
- \item The \key[index=false]{delims-\meta{\dots}} keys sets the delimiters used around the \meta{\dots}. The Rule of Two applies here: \enquote{Always two there are, no more, no less. A left and a right delimiter}. The allowed delimiters are those that can be scaled with \cs{left}, \cs{big} etc.
- \item The \key[index=false]{scale-\meta{\dots}} keys sets the size of the \meta{\dots}'s delimiters. The values \texttt{big}, \texttt{Big}, \texttt{bigg}, and \texttt{Bigg} are self-explanatory and internally a left and right version are used e.g. \cs{bigl} and \cs{bigr}. The value \texttt{none} inserts the delimiters (except periods) unscaled. While the value \texttt{auto} scales the delimiters automatically using \cs{left} and \cs{right}.
- \item The \key[index=false]{sep-\meta{\dots}-\meta{\dots}} keys inserts their value between \meta{\dots} and \meta{\dots}. If the value is a comma-separated list of up to three numbers (e.g. \texttt{\{x,y,z\}}) it will be converted into the syntax \texttt{\cs{muskip} x mu plus y mu minus z mu} and inserted. All other values are used as they were given.
- \item The \key[index=false]{switch-\meta{\dots}} keys serves to change an argument's behaviour by swapping the effect of an optional character's presence.
- \item The \key[index=false]{sort-\meta{\dots}} keys deals with the sorting algorithm behind the mixed order, where you can choose the sorting method that suits you best.
- \item The miscellaneous keys does not fit into any of the above categories and no longer have the prefix \key[index=false]{misc}
- \end{itemize}
-
- \begin{note}
- A value with superscripted \texttt{R} means it requires a package. Additionally, some keys have two versions; with and without \texttt{-/} at the end. These keys are related to the slash argument. If \keyval{switch-/}{false} then the keys with and without \texttt{-/} are used when the slash argument is present and absent, respectively. Setting \keyval{switch-/}{true} then these keys are used in the opposite cases of the slash argument's presence.
- \end{note}
-
- \subsection{Package options}
- The package options can be used with
- \begin{center}
- \ttfamily\small
- \cs{usepackage}\oarg{keyval list}\narg{derivative}
- \end{center}
-
- \begin{option}*{italic}[new = v1.1]
- \begin{values}[default = false]
- true, false
- \end{values}
- Sets the font-style of the infinitesimals $d$ and $D$ used in \cs{odv}, \cs{mdv}, \cs{odif} and \cs{mdif} to italic using \cs{mathnormal}. The options \key{italic} and \key{upright} are mutually exclusive.
- \end{option}
-
- \begin{option}{upright}[new = v1.1]
- \begin{values}[default = true]
- true, false
- \end{values}
- Sets the font-style of the infinitesimals $d$ and $D$ used in \cs{odv}, \cs{mdv}, \cs{odif} and \cs{mdif} to upright using \cs{mathrm}. The options \key{italic} and \key{upright} are mutually exclusive.
- \end{option}
-
- \subsection{Derivative options} \label{ssec:options_dv}
- The options in this subsection are available for derivatives defined by the package and you with the commands in \cref{ssec:defvar_dv}.
-
- \subsubsection*{Style}
-
- \begin{option}*{style-inf}[updated = v1.0]
- \begin{values}[default = d]
- \meta{math-font-style}\meta{infinitesimal}
- \end{values}
- Sets the derivative's infinitesimal including font style. This change was necessary to allow multiple font styles, e.g. \keyval{style-inf}{\cs{mathbf}\narg{\cs{mathrm}\narg{d}}}. The default infinitesimal is a plain `\default` with no associated font style.
- \end{option}
-
- \begin{option}{style-frac}
- \begin{values}[default = \cs{frac}]

+This package originated as a personal package I developed several years ago for various projects. Initially written in \tex{} and \latex{}, it encountered numerous errors as its complexity grew, eventually becoming a convoluted code. Consequently, I rewrote the code using the \latex3 language, allowing for easier maintenance. Originally, I created this package due to the lack of robust derivative packages available. However, I later discovered the \pkg{diffcoeff} package, which served the purpose well. Unfortunately, by that time, I had already written a most of the code, undocumented. To address this, I decided to document the code and transform it into a publicly available package.
+
+\bigskip
+
+Regarding terminology, I use the abbreviation \texttt{inf} to represent the operator symbols $d, \partial, \delta$, etc., commonly used in derivatives (e.g., $\odv{y}{x}, \pdv{y}{x}, \fdv{y}{x}$) and differentials (e.g., $\odif{x}, \pdif{x}, \fdif{x}$). In the description of macros and options, I often use the notation \emph{cs-\meta{placeholder}} to indicate a comma-separated list of \meta{placeholder}. For instance, \oarg{cs-numbers} is used in the option section to denote a comma-separated list of numbers for math space keys. It is important to note that whenever an argument specifies \meta{keyvalue list}, it refers to a comma-separated list of key-value pairs.

+\begin{function}*{\pdv}[updated=v1.3]
+ \begin{syntax}
+ \sarg, \oarg{keyval list}, \marg{function}, \targ{/}, \targ{!}, \marg{variables}, \earg{\_, point\tsb{1}, \^, point\tsb{2}}
+ \end{syntax}
+ The partial derivative is defined using the \macro{1} command, which has both mandatory and optional arguments. These arguments allow for the customization of specific parts and the style of the derivative.
+ \begin{definition}
+ \DeclareDerivative{\pdv}{\partial}[style-var=multiple, style-var-/=multiple,
+ style-var-!=mixed, style-var-/!=multiple, delims-eval=(), delims-eval-/=(),
+ delims-eval-!=()]
+ \end{definition}
+
+ \begin{argument}*{1}
+ The optional first argument of \macro{1} controls the placement of the function in relation to the fraction. By setting \keyval{switch-*}{false}, the function is typeset in the numerator when the star is absent, and next to the fraction when the star is present. Here is an example:
\begin{example}
- \pdv[switch-*=false]{y}{x} \\
- \pdv[switch-*=true]{y}{x}
+ \pdv{f}{x,y} \\
+ \pdv*{f}{x,y}
\end{example}

- \noindent respectively. The key's default value is \default.
- \end{option}
-
- \begin{option}{switch-/}
- \begin{values}[default = false]
- true, false
- \end{values}
- The effect of the slash argument's presence can be switched with the value \val{true}. That is, the derivative is typeset with the fraction set by \key{style-frac-/} when the slash is absent and with the fraction set by \key{style-frac} when the slash is present. As an example, compare below where the option is turned on (\val{true}) and off (\val{false})
-
+ The behavior of the star can be reversed by setting \keyval{switch-*}{true}. In other words, the equations in the previous example will be interchanged.
+ \end{argument}
+
+ \begin{argument}{2}[updated = v1.0]
+ The second argument of \macro{1}, enclosed in square brackets, is optional and used to specify options for the derivative using a \keyval[index=false]{key}{value} syntax. For instance, the order of differentiation can be set using the \key[cat=misc]{order} option. Here is an example:
\begin{example}
- \pdv[switch-/=false]{y}{x} \\
- \pdv[switch-/=true]{y}{x}
+ \pdv[order={2,3}]{f}{x,y,z} \\
+ \pdv[order={\beta,a,n+2a}]{f}{x,y,z} \\
+ \pdv[order={2,n^2,n^2-1}]{f}{x,y,z} \\
+ \pdv[order={3/2-n/3,n/2,1/3}]{f}{x,y,z}
\end{example}

-
- \begin{option}{switch-sort}[new = 1.2]
- \begin{values}[default = true]
- true, false
- \end{values}
- The sorting algorithm of the mixed order is turned on when given the value \val{true} i.e. the methods given in \keyval*{sort-method}{\dots} are applied. Likewise, the sorting algorithm is turned off when given the value \val{false} i.e. the terms in the mixed order are ordered by first appearance in \keyval*{order}{\dots}. As an example, compare below where the option is turned on (\val{true}) and off (\val{false})
-
+ For a comprehensive list of available options that can be applied to derivatives, please refer to \cref{ssec:options_dv}.
+ %The order may be a number, a symbol and a combination hereof. Note that the total order of differentiation (i.e $\odif[order=n+2]{}$) is automatically calculated and sorted. This is particularly useful when dealing with mixed partial derivatives which is further described in \cref{ssec:DV_pdv,ssec:overall_order}
+ \end{argument}
+
+ \begin{argument}{3}
+ The first mandatory argument of \macro{1} is used to typeset the function that will be differentiated. Here are some examples:
\begin{example}
- \pdv[switch-sort=false, order={a+b,2kn-d,2-2b}]{f}{x,y,z} \\
- \pdv[switch-sort=true, order={a+b,2kn-d,2-2b}]{f}{x,y,z}
+ \pdv{f(x,y,z)}{x,y,z} \\
+ \pdv{e^x\sin(y)\ln(z)}{x,y,z}
\end{example}
-

- \end{option}
-
- \subsubsection*{Sort}
- The keys given in this subsection will be briefly described here and a in-depth description will be given in \cref{ssec:overall_order}.
+ The function is displayed either in the numerator or to the right of the derivative, depending on the presence or absence of the star argument.
+ \end{argument}
- \begin{option}{sort-method}[updated = v1.2]
- \begin{values}[default = {sign, symbol, abs}]
- abs, lexical, number, sign, symbol
- \end{values}
- This key sets the sorting method behind the mixed order using build-in algorithms. The symbolic terms in the mixed order are sorted by their sign, symbolic length, numerical value and absolute value by the \val{sign}, \val{symbol}, \val{number} and \val{abs} algorithms, respectively. The value \val{lexical} sorts the terms by lexicographical order i.e. alphabetically. The key takes its input as a comma-separated list of values, accepting up to three values e.g.
+ \begin{argument}{4}[updated = v1.3]
+ The fourth argument of \macro{1} is an optional slash that appears between the function and the variable arguments, indicating an alternative style. Its behaviour depends on the presence or absence of the exclamation mark argument.
+ When the exclamation mark is absent, the slash determines the fraction style in which the derivative is typeset. By default, when the slash is absent, the derivative is typeset with \cs{frac}, and when the slash is present, it is typeset with \cs{slashfrac}\footnote{Note that \cs{slashfrac} is a macro defined by the package, please refer to \cref{ssec:slashfrac} for more details.\label{foot:sfrac}}, as shown in the following example:
\begin{example}
- \pdv[sort-method=abs, order={c+kn,-b+2a}]{f}{x,y} \\
- \pdv[sort-method=lexical, order={c+kn,-b+2a}]{f}{x,y} \\
- \pdv[sort-method=number, order={c+kn,-b+2a}]{f}{x,y} \\
- \pdv[sort-method=symbol, order={c+kn,-b+2a}]{f}{x,y} \\
- \pdv[sort-method=sign, order={c+kn,-b+2a}]{f}{x,y} \\
- \pdv[sort-method={sign,symbol}, order={c+kn,-b+2a}]{f}{x,y} \\
- \pdv[sort-method={sign,symbol,abs}, order={c+kn,-b+2a}]{f}{x,y}
+ \pdv{f}{x,y} \\
+ \pdv{f}/{x,y}
\end{example}
+ However, when the exclamation mark argument is present, the slash argument switches between shorthand styles rather than fraction styles.
- \noindent are all valid inputs. Note how the terms are ordered differently with different methods. This key is further described in \cref{ssec:sort-method}. The key's default value uses the three algorithms \val{\default}.
- \end{option}
-
- \begin{option}{sort-numerical}[updated = v1.0]
- \begin{values}[default = auto]
- auto, first, last, symbolic
- \end{values}
- This key determines where the numerical term\footnote{The numerical term is the sum of all the orders that does not contain any symbols but solely consist of numbers.\label{foot:numerical-term}} is placed in the mixed order. The numerical term will \emph{always} be placed as the first with \val{first} and as the last term with \val{last} in the mixed order. While \val{auto} will automatically determine where to place the numerical term depending on the sign of the first symbolic term. This is shown below
+ Similar to the star argument, the effect of the slash's presence can be reversed by setting \keyval{switch-/}{true}. In other words, the equations in the previous example will be interchanged.
+ \end{argument}
+
+ \begin{argument}{5}[new = v1.3]
+ The fifth argument of \macro{1} is an optional exclamation mark that appears between the function and the variable arguments. It allows switching the derivative into shorthand style, as described in \cref{ssec:options_dv}.
+ When \keyval{switch-!}{false} is used, along with the \macro{1}'s default shorthand styles, the derivative is typeset as shown in the example below:
\begin{example}
- \pdv[sort-numerical=first, order={n,2}]{f}{x,y} \\
- \pdv[sort-numerical=last, order={-n,2}]{f}{x,y}
+ \pdv{f}!{x,y} \\
+ \pdv{f}/!{x,y}
\end{example}
-
- \noindent where the value \val{auto} would have placed the numerical term opposite in both equations. The value \val{symbolic} treats the numerical term as a symbolic term with symbolic length equal zero and is thus sorted alongside with all other terms
+ The effect of the exclamation mark's presence can be reversed by setting \keyval{switch-!}{true}. In other words, the equations in the previous example will be interchanged.
+ \begin{note}
+ The order of the slash and exclamation mark is important. For example, \cs{pdv}\narg{f}\targ{!}\targ{/}\narg{x,y} will give $\pdv{f}!/{x,y}$ and not the indented output $\pdv{f}/!{x,y}$.
+ \end{note}
+ \end{argument}
+
+ \begin{argument}{6}
+ This is the second and final mandatory argument is used to typeset the variable in which the function is differentiated with respect to. The variables should be provided as a comma-separated list
\begin{example}
- \pdv[sort-numerical=symbolic, order={2+n,-a}]{f}{x,y}
+ \pdv{f}{x} \\
+ \pdv{f}{x,y}
\end{example}

+ The subscript argument is commonly used to indicate the point of evaluation or the variables held constant. If needed, the superscript argument can be used to denote a second point of evaluation.
+ \end{argument}
+\end{function}
+
+\subsection{Other derivatives}
+In addition to the partial derivative, the package also provides five other derivative commands:
+\begin{itemize}
+ \item Ordinary derivative: \macro{\odv} - Used to represent the rate of change of a single-variable function with respect to its independent variable.
+ \item Material derivative: \macro{\mdv} - Applied in fluid mechanics and continuum mechanics to describe the rate of change of a quantity attached to a moving fluid particle.
+ \item Functional derivative: \macro{\fdv} - Used in functional analysis, calculus of variations, and quantum mechanics to express the derivative of a functional.
+ \item Average rate of change: \macro{\adv} - Used to denote the average rate of change of a quantity over a given interval.
+ \item Jacobian: \macro{\jdv} - Significant in multivariable calculus and linear algebra for representing the derivative of a vector-valued function.
+\end{itemize}
+A unique feature of this package is that it allows you to define your own derivatives, as described in \cref{ssec:defvar_dv}. This means you can create custom derivative commands tailored to your specific needs.
+
+If you require more information on the usage and customization of these derivative commands, please refer to the documentation in \cref{ssec:defvar_dv}.

+ In this package, the ordinary derivative is defined with an upright lowercase d if the package option \keyval[cat=misc]{upright}{true} is used. Otherwise, it is defined with an italic lowercase \textit{d}. This choice was made to align with the convention used in many modern books.

+
+\begin{function}*{\odif}[new = v1.0, updated=v1.1]
+ \begin{syntax}
+ \sarg, \oarg{keyval list}, \marg{variables}
+ \end{syntax}
+ The differential \macro{1} is defined with both mandatory and optional arguments that allow for customizing its typesetting and style. It is defined with an upright lowercase d when \keyval[cat=misc]{upright}{true} is used. Otherwise, it will be defined with an italic lowercase d.
+ \begin{definition}
+ \DeclareDifferential{\odif}{\mathrm{d}}%\marginnote{\keyval[cat=misc]{upright}{true}}%
+ \DeclareDifferential{\odif}{\mathnormal{d}}%\marginnote{\keyval[cat=misc]{italic}{true}}%
+ \end{definition}
+
+ \begin{argument}*{1}
+ The first argument of \macro{1} is an optional star that determines the notation style of the differential. With the \keyval{switch-*}{false} option, the variables and orders are typeset as subscript and superscript, respectively, when the star is present. When the star is absent, the infinitesimal is placed in front of each variable, as illustrated below:
\begin{example}
- \pdv[frac=false]{f}{x,y,z} \\
- \pdv[frac=true]{f}{x,y,z} \\
- \pdv*[frac=true]{f}{x,y,z} \\
- \pdv[frac]{f}{x,y,z}
+ \odif{x,y,z} \\
+ \odif*{x,y,z}
\end{example}
- Without setting the option to a value is equivalent to setting it to \val{true} as seen above.
- \end{option}
-
- \begin{option}{var}[cat=misc, new = v1.0]
- \begin{values}[default=none]
- none, all, \meta{cs-numbers}
- \end{values}
- Adds or remove delimiters around the variable. The value \val{all} adds delimiters around all variables and \val{none} removed all delimiters. However, if only some variables needs delimiters then \meta{cs-numbers} can be used e.g. \keyval*[cat=misc]{var}{1,3} adds delimiters around the first and third variable
+ The behavior of the star can be reversed by setting \keyval{switch-*}{true}. In other words, the equations in the previous example will be interchanged.
+ \end{argument}
+
+ \begin{argument}{2}
+ The second argument, enclosed in square brackets, is optional and is used to specify options for the differential using the \keyval[index=false]{key}{value} syntax. Here are some examples:
\begin{example}
- \pdv[var=none]{f}{x,y,z,t} \\
- \pdv[var={1,3}]{f}{x,y,z,t} \\
- \pdv[var=all]{f}{x,y,z,t} \\
- \pdv[var]{f}{x,y,z,t}
+ \odif[order={n,3}]{x,y,z} \\
+ \odif[sep-var-inf=0]{x,y,z} \\
+ \odif*[sep-var-var=0]{x,y,z}

- In cases where it fails or another form is preferred, the calculated mixed order can be overwritten with this option.
- \end{option}

- \end{option}
-
- \begin{option}{style-notation}
- \begin{values}[default = multiple]
- single, multiple, mixed
- \end{values}

The value \val{single} creates a single differential with the variables and orders in a subscript and superscript, respectively. The value \val{multiple} creates a differentials for each variable. The value \val{mixed} creates multiple differentials with the variables and orders in a subscript and superscript, respectively.
-
+ \begin{argument}{3}

-
- \subsubsection*{Delimiters}
-
- \begin{option}{delims-var}
- \begin{values}[default = (~)]
- \meta{left delimiter}\meta{right delimiter}
- \end{values}
- Sets the left and right delimiters used around the variable when the star argument is absent (given \keyval{switch-*}{false}). The delimiters are inserted when \keyval[cat=misc]{var}{true} is used. The key's default delimiters are a left and right parenthesis, respectively.

- \subsubsection*{Miscellaneous}
+ \clearpage
+ \section{Options}
+This package accepts its options using the familiar \emph{key=value} syntax. The keys are divided into categories, with each key having its associated category as a prefix.
+
+\begin{function}{\derivset}[updated = v1.0]
+ \begin{syntax}
+ \marg{command}, \oarg{keyval list}
+ \end{syntax}
+ The \macro{1} command is used to set default values for derivative and differential options in the preamble. While it can be used within the document, the new \oarg{keyval list} arguments in the derivative and differential commands allow for more flexibility in specifying options on a per-use basis.
- \begin{option}*{var}[cat=misc]
- \begin{values}[default=none]
- none, all, \meta{cs-numbers}
- \end{values}
- Adds or remove delimiters around the variable. The value \val{all} adds delimiters around all variables and \val{none} removed all delimiters. However, if only some variables needs delimiters then \meta{cs-numbers} can be used e.g. \keyval*[cat=misc]{var}{1,3} adds delimiters around the first and third variable
+ \begin{argument}{1}
+ The mandatory argument determines which command the \emph{key=value} pairs are assigned to. The allowed \meta{commands} are the derivatives and differentials defined by the package, as well as any additional derivatives and differentials you have defined (see \cref{ssec:defvar_dv,ssec:defvar_inf} for more information). Additionally, the special value \texttt{all} is allowed, which provides access to the options that apply to all derivatives and differentials.
\begin{example}
- \odif[var=none]{x,y,z,t} \\
- \odif[var={1,3}]{x,y,z,t} \\
- \odif[var=all]{x,y,z,t} \\
- \odif[var]{x,y,z,t}
+ \derivset{\odv}[switch-*=true] \odv{y}{x} \\
+ \derivset{\odif}[switch-*=true] \odif{y}{x}
\end{example}
- Without setting the option to a value is equivalent to setting it to \val{all} as seen above.
- \end{option}
-
- \begin{option}{order, ord}[cat=misc]
- \begin{values}[default = 1]
- \marg{cs-orders}
- \end{values}
- Sets the differentiation order of each variable.
- \end{option}
-
- \subsection{All derivatives and differentials} \label{ssec:both_options}
- The options in this subsection are applied to all derivatives and differential because some options should be consisting regardless of the derivative and differential. The options are accessed using \macro{\derivset}[\narg{all},\oarg{key=value}].
-
- \begin{option}{scale-auto}[updated = v1.1]
- \begin{values}[default = {leftright, mleftmright\req}]
- leftright, mleftmright\req
- \end{values}
- Sets the dynamic scaling methods of delimiters. The value \val{leftright} sets the method to use \cs{left} and \cs{right}. The value \val{mleftmright} requires the \pkg{mleftright} package and sets the method to use \cs{mleft} and \cs{mright} instead. The default value is \val{leftright} unless \pkg{mleftright} have been loaded then it is \val{mleftmright}.
- \end{option}
+ \end{argument}
+ \begin{argument}{2}
+ The optional argument accepts input as a comma-separated list of \emph{key=value} pairs. If \arg{2} is omitted, the options will be set to the package's default settings for the chosen \arg{1}. For example, using the \macro{\derivset}[\narg{\macro{\odv}}] command will set the options for the ordinary derivative to the default settings defined by the package.
+ \begin{example}
+ \derivset{\odv}[switch-*=false] \odv{y}{x} \odv*{y}{x} \\
+ \derivset{\odv}[switch-*=true] \odv{y}{x} \odv*{y}{x} \\
+ \derivset{\odv} \odv{y}{x} \odv*{y}{x}
+ \end{example}
+ \end{argument}
+\end{function}
+
+\subsection{Categories}
+This section seeks to give a detailed description of each category.
+
+\begin{itemize}
+ \item The \key[index=false]{style-\meta{\dots}} keys allow you to customize the style of derivatives or differentials by specifying options such as the fraction command, infinitesimal notation (e.g., $d$, $\partial$) and its font, and variable treatment.
+ \item The \key[index=false]{delims-\meta{\dots}} keys sets the delimiters used around the \meta{\dots}. The Rule of Two applies: \enquote{Always two there are, no more, no less. A left and a right delimiter}. Only delimiters that can be scaled with commands like \cs{left}, \cs{big}, etc., are allowed.
+ \item The \key[index=false]{scale-\meta{\dots}} keys sets the size of the \meta{\dots}'s delimiters. The values \val{big}, \val{Big}, \val{bigg}, and \val{Bigg} are self-explanatory. The value \val{none} leaves the delimiters unscaled (except for periods, which are removed). The value \val{auto} automatically scales the delimiters using \cs{left} and \cs{right}.
+ \item The \key[index=false]{sep-\meta{\dots}-\meta{\dots}} keys inserts their value between \meta{\dots} and \meta{\dots}. If the value is a comma-separated list of up to three numbers (e.g. \texttt{\{1,2,3\}}) it is converted into the syntax \texttt{\cs{muskip} 1 mu plus 2 mu minus 3 mu} and used accordingly. For other values, they are used as given without any conversion.
+ \item The \key[index=false]{switch-\meta{\dots}} keys allow you to change the behaviour of an argument by swapping the effect of the presence or absence of an optional character argument.
+ \item The \key[index=false]{sort-\meta{\dots}} keys handle the sorting algorithm used for the mixed order. These keys allow you to choose the sorting method that best suits your preferences.
+ \item The miscellaneous keys do not fall into any of the previously mentioned categories and does not have a prefix.

+
+\begin{note}
+ A value with a superscripted \texttt{R} indicates that it requires a specific package to be loaded. Additionally, some keys have multiple versions, denoted by \texttt{-/}, \texttt{-!}, and \texttt{-/!} at the end. These keys are specifically related to the slash and exclamation mark arguments.

+\subsection{Derivative options} \label{ssec:options_dv}
+The options in this subsection are available fo customizing the behaviour of derivatives defined by the package and you.% using the commands described in \cref{ssec:defvar_dv}.
+
+\subsubsection*{Style}
+
+\begin{option}*{style-inf}[updated = {v1.0, v1.3}]
+ \begin{values}[default = ]
+ \meta{math-font-style}\meta{infinitesimal}
+ \end{values}
+ Sets the infinitesimal used in the derivative. This is a meta key, which means it sets the value of both \key{style-inf-num} and \key{style-inf-den} at the same time.
+ \begin{example}
+ \odv[style-inf=\symbf{d}]{f}{x}
+ \end{example}
+\end{option}
+
+\begin{option}{style-inf-num}[new = v1.3]
+ \begin{values}[default = d]
+ \meta{math-font-style}\meta{infinitesimal}
+ \end{values}
+ Sets the infinitesimal used in the numerator of the derivative. This option is also used in the shorthand versions, i.e., when the exclamation mark argument is used. The default infinitesimal is a plain \default.
+ \begin{example}
+ \odv[style-inf-num=\mathbf{d}]{f}{x} \\
+ \odv[style-inf-num=\mathbf{d}]{f}!{x}
+ \end{example}
+\end{option}
+
+\begin{option}{style-inf-den}[new = v1.3]
+ \begin{values}[default = d]
+ \meta{math-font-style}\meta{infinitesimal}
+ \end{values}
+ Sets the infinitesimal used in the denominator of the derivative. The default infinitesimal is a plain \default.
+ \begin{example}
+ \odv[style-inf-den=\mathbf{d}]{f}{x}
+ \end{example}
+\end{option}
+
+\begin{option}{style-frac}
+ \begin{values}[default = \cs{frac}]
+ \meta{fraction}
+ \end{values}
+ The derivative uses the fraction set by this key when the slash argument is absent. If \keyval{switch-/}{true}, the derivative uses this fraction when the slash argument is present. The key's default value is the usual fraction \cs{frac}.
+ \begin{example}
+ \odv[style-frac=\tfrac]{f}{x} \\
+ \odv[switch-/=true, style-frac=\tfrac]{f}/{x}
+ \end{example}
+\end{option}
+
+\begin{option}{style-frac-/}
+ \begin{values}[default = \cs{slashfrac}]
+ \meta{fraction}
+ \end{values}
+ The derivative uses the fraction set by this key when the slash argument is present. If \keyval{switch-/}{true}, the derivative uses this fraction when the slash argument is absent. The key's default value is a text-styled fraction \val{\default}\footref{foot:sfrac} on the form $\odv[style-frac-/=\slashfrac, switch-/=false]{f}/{x}$.
+ \begin{example}
+ \odv[style-frac-/=\sfrac]{f}/{x}
+ \end{example}
+\end{option}
+
+\begin{option}{style-var}[new = v1.0]
+ \begin{values}[default = single]
+ single, multiple
+ \end{values}
+ This option determines how the derivative treats its variables and orders when both the slash argument and the exclamation mark are absent assuming \keyval{switch-/}{false} and \keyval{switch-!}{false}
+ \begin{itemize}[widest = {\val{multiple}}, leftmargin =*]
+ \item[\val{single}] The derivative behaves like a ordinary derivative, treating the variable argument and order as single entities.
+ \item[\val{multiple}] The derivative behaves like a partial derivative, treating the variable argument as a list of comma-separated variables. The mixed order is automatically calculated and sorted based on the \keyval[cat=misc]{order}{\meta{cs-orders}} key. See \cref{ssec:overall_order} for limitations on the automatic calculation.
+ \end{itemize}
+ %This option determines how the derivative treats its variables. The variable argument is treated as a single variable and the order is treated as a single order when \val{single} is used. The variable argument is treated as a comma separated list of variables with \val{multiple} similarly to a partial derivative. Moreover the mixed order is automatically calculated from the list of orders given in \keyval[cat=misc]{order}{\meta{order}}.
+ \begin{example}
+ \pdv[style-var=single, order={1,2,3}]{f}{x,y,z} \\
+ \pdv[style-var=multiple]{f}{x,y,z}
+ \end{example}
+\end{option}
+
+\begin{option}{style-var-/}[new = v1.3]
+ \begin{values}[default = single]
+ single, multiple
+ \end{values}
+ This option behaves identically to \key{style-var}, however it is used when the slash argument is present and the exclamation mark is absent assuming \keyval{switch-/}{false} and \keyval{switch-!}{false}.
+ \begin{example}
+ \pdv[style-var-/=single, order={1,2,3}]{f}/{x,y,z} \\
+ \pdv[style-var-/=multiple]{f}/{x,y,z}
+ \end{example}
+\end{option}
+
+\begin{option}{style-var-!}[new = v1.3]
+ \begin{values}[default = multiple]
+ single, multiple, mixed
+ \end{values}
+ This options determines the shorthand notation of the derivative when the slash argument is absent and the exclamation mark is present assuming \keyval{switch-/}{false} and \keyval{switch-!}{false}.
+ \begin{itemize}[widest = {\val{multiple}}, leftmargin =*]
+ \item[\val{single}] Creates a single differential with variables as subscripts and orders as superscripts.
+ \item[\val{multiple}] Creates a separate differential for each variable.
+ \item[\val{mixed}] Creates a separate differential for each variable but with variables as subscripts and orders as superscripts.
+ \end{itemize}
+ %When \val{single} is used, a single differential is created with the variables and orders in a subscript and superscript, respectively. The value \val{multiple} creates a differential for each variable. While the value \val{mixed} creates differentials their variable and order in a subscript and superscript, respectively.
+ \begin{example}
+ \pdv[style-var-!=single]{f}!{x,y,z} \\
+ \pdv[style-var-!=multiple]{f}!{x,y,z} \\
+ \pdv[style-var-!=mixed]{f}!{x,y,z}
+ \end{example}
+\end{option}
+
+\begin{option}{style-var-/!}[new = v1.3]
+ \begin{values}[default = single]
+ single, multiple, mixed
+ \end{values}
+ This option behaves identical to \key{style-var-!}, however it is used when both the exclamation mark and slash arguments are present assuming \keyval{switch-/}{false} and \keyval{switch-!}{false}.
+ \begin{example}
+ \pdv[style-var-/!=single]{f}/!{x,y,z} \\
+ \pdv[style-var-/!=multiple]{f}/!{x,y,z} \\
+ \pdv[style-var-/!=mixed]{f}/!{x,y,z}
+ \end{example}
+\end{option}
+

+ auto, none, big, Big, bigg, Bigg
+ \end{values}

+ \meta{cs-number}, \marg{mspace}, \marg{delimiter}
+ \end{values}
+ Sets the separator that is inserted in the evaluation subscript left to the point of evaluation when a \emph{non-blank} subscript is given. The default value corresponds to \val{\default} \texttt{mu}.
+ \begin{example}
+ \pdv[sep-eval-sb=\here]{f}{x,y}_{(x_1,y_1)}
+ \end{example}
+\end{option}
+
+\begin{option}{sep-eval-sp}
+ \begin{values}[default = 0]
+ \meta{cs-number}, \marg{mspace}, \marg{delimiter}
+ \end{values}
+ Sets the separator that is inserted in the evaluation superscript left to the point of evaluation when a \emph{non-blank} superscript is given. The default value corresponds to \val{\default} \texttt{mu}.
+ \begin{example}
+ \pdv[sep-eval-sp=\here]{f}{x,y}^{(x_2,y_2)}
+ \end{example}
+\end{option}
+
+\subsubsection*{Switches}
+
+\begin{option}*{switch-*}
+ \begin{values}[default = false]
+ true, false
+ \end{values}
+ The effect of the star argument can be toggled with the value \val{true}.
+ %That is, the function is typeset next to the fraction when the star is absent and in the numerator when the star is present.
+ For example, compare below where the option is disabled (\val{false}) and enabled (\val{true}). The default value is \val{\default}.
+ \begin{example}
+ \pdv[switch-*=false]{f}{x,y} \\
+ \pdv[switch-*=true]{f}{x,y}
+ \end{example}
+\end{option}
+
+\begin{option}{switch-/}
+ \begin{values}[default = false]
+ true, false
+ \end{values}
+ The effect of the slash argument can be toggled with the value \val{true}.
+ %That is, the derivative is typeset with the fraction set by \key{style-frac-/} when the slash is absent and with the fraction set by \key{style-frac} when the slash is present.
+ For example, compare below where the option is disabled (\val{false}) and enabled (\val{true}). The default value is \val{\default}.
+ \begin{example}
+ \pdv[switch-/=false]{f}{x,y} \\
+ \pdv[switch-/=true]{f}{x,y}
+ \end{example}
+\end{option}
+
+\begin{option}{switch-!}[new = 1.3]
+ \begin{values}[default = false]
+ true, false
+ \end{values}
+ The effect of the exclamation mark argument can be toggled with the value \val{true}.
+ %That is, the derivative is in shorthand mode the exclamation mark is absent and in fraction mode when the exclamation is present.
+ For example, compare below where the option is disabled (\val{false}) and enabled (\val{true}). The default value is \val{\default}.
+ \begin{example}
+ \pdv[switch-!=false]{f}{x,y} \\
+ \pdv[switch-!=true]{f}{x,y}
+ \end{example}
+\end{option}
+
+\begin{option}{switch-sort}[new = 1.2]
+ \begin{values}[default = true]
+ true, false
+ \end{values}
+ This options disables (\val{false}) and enables (\val{true}) the sorting algorithm behind the mixed order. The sorting algorithm is only used/available in fraction mode when it is \val{multiple}. When disabled, the terms in the mixed order are arranged according to their first appearance in \keyval*[cat=misc,index=false]{order}{\dots}. Compare below where the option is disabled (\val{false}) and enabled (\val{true}). The default value is \val{\default}.
+ %When the value \val{true} is given, the mixed order sorting algorithm is activated, applying the methods specified in \keyval*{sort-method}{\dots}. Conversely, when the value \val{false} is given, the sorting algorithm is deactivated, and the terms in the mixed order are arranged according to their first appearance in \keyval*{order}{\dots}. Here's a comparison example with the option enabled (\val{true}) and disabled (\val{false}).
+ \begin{example}
+ \pdv[switch-sort=false, order={a+b,2kn-d,2-2b}]{f}{x,y,z} \\
+ \pdv[switch-sort=true, order={a+b,2kn-d,2-2b}]{f}{x,y,z}
+ \end{example}
+\end{option}
+
+\subsubsection*{Sort}
+The keys mentioned in this subsection will be briefly described here, with a more detailed explanation provided in \cref{ssec:overall_order}.
+
+\begin{option}{sort-method}[updated = v1.2]
+ \begin{values}[default = {sign, symbol, abs}]
+ abs, lexical, number, sign, symbol
+ \end{values}
+ Sets the sorting method for the mixed order using build-in algorithms.
+ \begin{itemize}[widest = {\val{lexical}}, leftmargin =*]
+ \item[\val{abs}] Sorts terms in descending order based on their absolute value.
+ \item[\val{lexical}] Sorts terms alphabetically in lexicographical ascending order.
+ \item[\val{number}] Sorts terms in descending order based on their numerical value.
+ \item[\val{sign}] Sorts terms by their sign, placing positive terms before the negative terms.
+ \item[\val{symbol}] Sorts terms in descending order based on their symbolic length.
+ \end{itemize}
+ This option accepts a comma-separated list of values, allowing up to three values. For example:
+ \begin{example}
+ \pdv[sort-method=abs, order={kn-c,2a-3b}]{f}{x,y} \\
+ \pdv[sort-method=lexical, order={kn-c,2a-3b}]{f}{x,y} \\
+ \pdv[sort-method=number, order={kn-c,2a-3b}]{f}{x,y} \\
+ \pdv[sort-method=symbol, order={kn-c,2a-3b}]{f}{x,y} \\
+ \pdv[sort-method=sign, order={kn-c,2a-3b}]{f}{x,y} \\
+ \pdv[sort-method={sign,abs}, order={kn-c,2a-3b}]{f}{x,y} \\
+ \pdv[sort-method={sign,symbol,abs}, order={kn-c,2a-3b}]{f}{x,y}
+ \end{example}
+ Notice the different term ordering achieved with each method. For a more detailed explanation of this key, see \cref{ssec:sort-method} for more information. The default value uses the three algorithms \val{\default}.
+\end{option}
+
+\begin{option}{sort-numerical}[updated = v1.0]
+ \begin{values}[default = auto]
+ auto, first, last, symbolic
+ \end{values}
+ Determines the placement of the numerical term\footnote{The numerical term refers to the sum of all orders that consist solely of numbers and do not include any symbols.\label{foot:numerical-term}} in the mixed order. The placement options are as follows:
+ \begin{itemize}[widest=\val{symbolic}, leftmargin=*]
+ \item[\val{first}] Always places the numerical term as the first term in the mixed order.
+ \item[\val{last}] Always places the numerical term as the last term in the mixed order.
+ \item[\val{auto}] After sorting, the numerical term is automatically positioned based on the sign of the first symbolic term. If positive, the numerical term is placed last. If negative, the numerical term is placed first.
+ \item[\val{symbolic}] Treats the numerical term as a symbolic term with a symbolic length of zero and sorts it alongside all other terms.
+ \end{itemize}
+ Here are some examples to illustrate the different placements of the numerical term:
+ \begin{example}
+ \pdv[sort-numerical=first, order={n,2}]{f}{x,y} \\
+ \pdv[sort-numerical=last, order={-n,2}]{f}{x,y} \\
+ \pdv[sort-numerical=auto, order={n,2}]{f}{x,y} \\
+ \pdv[sort-numerical=auto, order={-n,2}]{f}{x,y} \\
+ \pdv[sort-numerical=symbolic, order={2+n,-a}]{f}{x,y}
+ \end{example}
+ This key is further described in \cref{ssec:sort-numerical}. The default value is \val{\default}.
+\end{option}
+
+\begin{option}{sort-abs-reverse}
+ \begin{values}[default = false]
+ true, false
+ \end{values}

+ \begin{example}
+ \pdv[sort-abs-reverse=false, sort-method=abs, order=2a-3b]{f}{x} \\
+ \pdv[sort-abs-reverse=true, sort-method=abs, order=2a-3b]{f}{x}
+ \end{example}
+\end{option}
+
+\begin{option}{sort-lexical-reverse}[new = v1.2]
+ \begin{values}[default = false]
+ true, false
+ \end{values}

+ \pdv[sort-lexical-reverse=true, sort-method=lexical, order=a+b]{f}{x}
+ \end{example}
+\end{option}
+
+\begin{option}{sort-number-reverse}[new = v1.0]
+ \begin{values}[default = false]
+ true, false
+ \end{values}
+ When the value \val{true} is used with this option, the sorting order is reversed to ascending order. See \cref{ssec:sort-reverse} for more information.
+ \begin{example}
+ \pdv[sort-number-reverse=false, sort-method=number, order=2a-3b]{f}{x} \\
+ \pdv[sort-number-reverse=true, sort-method=number, order=2a-3b]{f}{x}
+ \end{example}
+\end{option}
+
+\begin{option}{sort-sign-reverse}
+ \begin{values}[default = false]
+ true, false
+ \end{values}
+ When the value \val{true} is used with this option, the sorting order is reversed, placing negative terms before the positive terms. See \cref{ssec:sort-reverse} for more information.
+ \begin{example}
+ \pdv[sort-sign-reverse=false, sort-method=sign, order=a-b]{f}{x} \\
+ \pdv[sort-sign-reverse=true, sort-method=sign, order=a-b]{f}{x}
+ \end{example}
+\end{option}
+
+\begin{option}{sort-symbol-reverse}
+ \begin{values}[default = false]
+ true, false
+ \end{values}
+ When the value \val{true} is used with this option, the sorting order is reversed to ascending order. See \cref{ssec:sort-reverse} for more information.
+ \begin{example}

+ \pdv[sort-symbol-reverse=true, sort-method=symbol, order=ab+c]{f}{x}
+ \end{example}
+\end{option}
+
+\subsubsection*{Miscellaneous}
+
+\begin{option}*{fun}[cat=misc, new = v1.0]
+ \begin{values}[default = false]
+ true, false
+ \end{values}
+ This option allows you to add (\val{true}) or remove (\val{false}) delimiters around the function. Note that if the option is not explicitly set, it is considered equivalent to \keyval[cat=misc,index=false]{fun}{true}. By default, the value is \val{\default}.
+ \begin{example}
+ \pdv[fun=false]{f}{x} \\
+ \pdv[fun=true]{f}{x} \\
+ \pdv[fun]{f}{x}
+ \end{example}
+ %Without setting the option to a value is equivalent to setting it to \val{true} as seen above.
+\end{option}
+
+\begin{option}{frac}[cat=misc, new = v1.0]
+ \begin{values}[default = false]
+ true, false
+ \end{values}
+ This option allows you to add (\val{true}) or remove (\val{false}) delimiters around the fractional part of the derivative. Note that if the option is not explicitly set, it is considered equivalent to \keyval[cat=misc,index=false]{frac}{true}. By default, the value is \val{\default}.
+ \begin{example}
+ \pdv[frac=false]{f}{x} \\
+ \pdv[frac=true]{f}{x} \\
+ \pdv*[frac=true]{f}{x} \\
+ \pdv[frac]{f}{x}
+ \end{example}
+\end{option}
+
+\begin{option}{var}[cat=misc, new = v1.0]
+ \begin{values}[default=none]
+ none, all, \meta{cs-numbers}
+ \end{values}
+ This option allows you to add or remove delimiters around the variables. The value \val{all} adds delimiters around all variables and \val{none} removed all delimiters. If only specific variables require delimiters, you can use \meta{cs-numbers}. For example, \keyval*[cat=misc,index=false]{var}{1,3} adds delimiters around the first and third variables. Note that if the option is not explicitly set, it is considered equivalent to \keyval[cat=misc,index=false]{var}{all}. By default, the value is \val{\default}.
+ \begin{example}
+ \pdv[var=none]{f}{x,y,z,t} \\
+ \pdv[var={1,3}]{f}{x,y,z,t} \\
+ \pdv[var=all]{f}{x,y,z,t} \\

+ \begin{values}[default = 1]
+ \marg{cs-orders}
+ \end{values}
+ Sets the order of differentiation for each variable as a comma separated list of values.
+ \begin{example}
+ \pdv[order={2,3}]{f}{x,y,z} \\
+ \pdv[order={\beta,a,n+2a}]{f}{x,y,z} \\
+ \pdv[order={2,n^2,n^2-1}]{f}{x,y,z} \\
+ \pdv[order={3/2-n/3,n/2,1/3}]{f}{x,y,z}
+ \end{example}
+\end{option}
+
+\begin{option}{mixed-order, mixord}[cat=misc, new = v1.0]
+ \begin{values}[default = 1]
+ \marg{mixed order}
+ \end{values}
+ This option allows you to manually specify the mixed order of differentiation, overriding the automatically calculated value based on the orders set by \keyval[cat=misc]{order}{\marg{orders}}. In cases where the automatic calculation fails or when a different form is preferred, you can use this option to set the desired mixed order.
+ \begin{example}
+ \pdv[order={n+3k, n-k}]{f}{x,y} \\
+ \pdv[order={n+3k, n-k}, mixed-order={2(n+k)}]{f}{x,y}
+ \end{example}
+\end{option}

- \subsection{Sorting algorithms} \label{ssec:sort-method}
- A unique feature of this package is that the sorting method behind the mixed order may be changed using built-in algorithms and there are currently four available: \val{abs}, \val{number}, \val{sign} and \val{symbol}. The algorithms have been chosen such that it the terms in the mixed order may be arranged in many ways with as few algorithms as possible to suit your liking. A sorting method may consist of up to three algorithms which are applied in layers.

The difference between the commands is as follows:

+ Examples of their use can be found in \cref{sec:differential}.
- When using the option \keyval{sort-method}{\{...\}}, the number of algorithms determines the number of layers e.g. \keyval*{sort-method}{sign,symbol} is a sorting method with two layers, where the algorithms \val{sign} and \val{symbol} are applied in layer \num{1} and layer \num{2}, respectively. E.i the \val{sign} algorithm splits the terms into two groups, one with positive terms and one with negative terms. Then the \val{symbol} algorithm will sorts the terms within each groups according to the terms symbolic length. The mixed order is then formed by combining these two groups.
+ \begin{argument}{1}
+ The first argument specifies the macro name of the differential being defined.
+ \end{argument}
- \subsubsection{Examples}
- The examples below are uses partial derivatives with \keyval*[cat=misc]{order}{3a-3hh-2b, 4c+4gg+2ff, -5d-5ee} and a close up view of the mixed order. Square brackets are used to indicate grouping of terms and the text below a group refers to the algorithm applied. Here the words positive and negative, long and short, and big and low refers to the \val{sign}, \val{symbol}, and \val{abs} algorithms, respectively. A row of square brackets represents a layer.
+ \begin{argument}{2}
+ The second argument sets the infinitesimal of the differential \arg{1}. It is equivalent to setting \keyval{style-inf}{\arg{2}}.
+ \end{argument}
- The packages default sorting method is \keyval*{sort-method}{sign,symbol,abs} which is used below. The \val{sign} algorithm separate the positive and negative terms in the first layer. While in the second layer, the terms are separated by symbol length etc.
- \begin{equation*}
- \pdv[sort-method = {sign,symbol,abs}, order={3a-3hh-2b, 4c+4gg+2ff, -5d-5ee}]{f}{x,y,z}
- \end{equation*}

- \end{equation*}
- as expected. Interchanging \val{sign} and \val{symbol} from the previous example i.e \keyval*{sort-method}{symbol,sign,abs}, then the \val{symbol} and \val{sign} algorithms are now applied in the first and second layer, respectively. The result is shown below
- \begin{equation*}
- \pdv[sort-method = {symbol,sign,abs}, order={3a-3hh-2b, 4c+4gg+2ff, -5d-5ee}]{f}{x,y,z}

+ \section{The mixed order} \label{ssec:overall_order}
+The algorithm used to calculate the mixed order is advanced and can handle a wide range of inputs, including numbers, symbols and fractions. It accurately parses the orders to generate the appropriate mixed order. Let's consider some examples to illustrate its capabilities:
+\begin{example}
+ \pdv[order={n+1,2}]{f}{x,y}\\
+ \pdv[order={n+1,2n}]{f}{x,y}\\
+ \pdv[order={n^2,n^2}]{f}{x,y}\\
+ \pdv[order={2/n-1/2, 3/n+m/3}]{f}{x,y,z}
+\end{example}
+The algorithm handles these cases and calculates the mixed order correctly. However, there are certain limitations when dealing with parentheses, except for a specific case where there is a single term in the denominator.
+\begin{example}
+ \pdv[order={2/n-1/2, 3/(2n)+m/3}]{f}{x,y}\\
+ \pdv[order={(2n+m)/3, 3n+m/3}]{f}{x,y}\\
+ \pdv[order={2/(2n+m), 1/(2(2n+m))}]{f}{x,y}
+\end{example}
+In the third equation, the mixed order doesn't make sense because the algorithm splits up the orders at $+$ and $-$ within parentheses without evaluating them correctly. For example, $2/(2n+m), 1/(2(2n+m))$ is incorrectly split into $2/(2n, m), 1/(2(2n, m))$. The same happens in the second equation. To address this limitation, the package provides the \key[cat=misc]{mixed-order} option, which overrides the incorrect output. You can specify the desired mixed order manually.
+\begin{example}
+ \pdv[order={(2n+m)/3, 3n+m/3}, mixord=8n/3+2m/3]{f}{x,y}\\
+ \pdv[order={2/(2n+m), 1/(2(2n+m))}, mixord=5/(2(2n+m))]{f}{x,y}
+\end{example}
+By using the \key[cat=misc]{mixed-order} option, you can ensure that the mixed order is displayed correctly, even when the algorithm's output may be incorrect or when a different form is preferred.
+
+\subsection{Sorting algorithms} \label{ssec:sort-method}
+A unique feature of this package is that the sorting method behind the mixed order may be changed using built-in algorithms. These algorithms are designed to offer variety of ways to sort the mixed order according to ones preferences.
+\begin{itemize}[widest = {\val{lexical}}, leftmargin =*]
+ \item[\val{abs}] Sorts terms based on their absolute value in descending order. By setting \keyval{sort-abs-reverse}{true}, terms are sorted in ascending order instead.
+ \item[\val{lexical}] Sorts the terms alphabetically in lexicographical order. By setting \keyval{sort-lexical-reverse}{true}, terms are sorted in reverse lexicographical order.
+ \item[\val{number}] Sorts terms based on their numerical value in descending order. By setting \keyval{sort-number-reverse}{true}, terms are sorted in ascending order instead.
+ \item[\val{sign}] Sorts terms by their sign, placing positive terms before negative terms. By setting, \keyval{sort-sign-reverse}{true}, places negative terms before positive terms.
+ \item[\val{symbol}] Sorts terms in descending order based on their symbolic length. By setting \keyval{sort-symbol-reverse}{true}, terms are sorted in ascending order instead.
+\end{itemize}
+
+The sorting method allows up to three algorithms given by \keyval*{sort-method}{algorithm1, algorithm2, algorithm3}. The list of orders is primarily sorted based on algorithm 1's condition. In case of ties, algorithm 2 is used for further sorting, and so on.
+
+Consider the list \texttt{\{a,-c,-b,d\}} and the sorting method \keyval*{sort-method}{sign,lexical}. Initially, the \val{sign} algorithm sorts the list as \texttt{\{a,d,-c,-b\}}. However, due to ties, other valid orderings exist like \texttt{\{d,a,-c,-b\}}, \texttt{\{a,d,-b,-c\}} and \texttt{\{d,a,-b,-c\}}. Subsequently, the \val{lexical} algorithm sorts the tied values alphabetically as \texttt{\{a,d,-b,-c\}}.
+
+\subsubsection{Examples}
+The examples below use partial derivatives with \keyval*[cat=misc]{order}{3a-3hh-2b, 4c+4gg+2ff, -5d-5ee}, along with a close-up view of the mixed order. Square brackets indicate how the terms was sorted by the applied algorithm. `Positive' and `negative', `long' and `short', and `big' and `low' refer to the \val{sign}, \val{symbol}, and \val{abs} algorithms, respectively.
+
+The default sorting method is \keyval*{sort-method}{sign,symbol,abs} which is used below. The \val{sign} algorithm separate the positive and negative terms. Within each group, the \val{symbol} algorithm sorts the terms based on symbolic length. Finally, In the resulting four groups, the \val{abs} algorithm sorts the terms based on absolute value.
+\begin{gather*}
+ \pdv[sort-method = {sign,symbol,abs}, order={3a-3hh-2b, 4c+4gg+2ff, -5d-5ee}]{f}{x,y,z} \\
+ \low{
\low{
- \low{
- \low{4gg}{big} +
- \low[2,2]{2ff}{low}
- }{positive} -
- \low{
- \low[3,3]{5ee}{big} -
- \low[2,2]{3hh}{low}
- }{negative}
+ \low{4gg}{big} +
+ \low[2,2]{2ff}{low}
}{long} +
+ \low{
+ \low[1,2]{4c}{big} +
+ \low[1,1]{3a}{low}

- \low[2,2]{2b}{low}
- }{negative}
+ \low[1,1]{5d}{big} -
+ \low[2,2]{2b}{low}
}{short}
- \end{equation*}
- where a clear difference is seen between the above two examples.
-
- The above two examples used 3-layer sorting methods but as mentioned earlier, the sorting method can also be constructed with one and two algorithms i.e. 1-layer and 2-layer sorting methods. A sorting method with two layers could be constructed as \keyval*{sort-method}{sign,symbol} and the terms are ordered by sign and then symbolic length. In this case, there is not a third layer
- \begin{equation*}
- \pdv[sort-method = {sign,symbol}, order={3a-3hh-2b, 4c+4gg+2ff, -5d-5ee}]{f}{x,y,z}
- \end{equation*}
- \begin{equation*}
+ }{negative}
+\end{gather*}
+By interchanging the \val{sign} and \val{symbol} algorithm in the previous example, then the \val{symbol} algorithm will be applied first and the \val{sign} algorithm handles the symbolic ties.
+\begin{gather*}
+ \pdv[sort-method = {symbol,sign,abs}, order={3a-3hh-2b, 4c+4gg+2ff, -5d-5ee}]{f}{x,y,z} \\
+ \low{
\low{
- \low{ 4gg + 2ff }{long} +
- \low{ 3a + 4c }{short}
+ \low{4gg}{big} +
+ \low[2,2]{2ff}{low}
}{positive} -
\low{
- \low{ 3hh - 5ee }{long} -
- \low{ 2b - 5d }{short}
+ \low[3,3]{5ee}{big} -
+ \low[2,2]{3hh}{low}
}{negative}
- \end{equation*}
- The last example shows a 1-layer sorting method given as \keyval{sort-method}{symbol} which gives the result
- \begin{equation*}
- \pdv[sort-method = symbol, order={3a-3hh-2b, 4c+4gg+2ff, -5d-5ee}]{f}{x,y,z}
- \end{equation*}
- \begin{equation*}
- \low{ - 3hh + 4gg + 2ff - 5ee }{long} +
- \low{ 3a - 2b + 4c - 5d }{short}
- \end{equation*}
- as expected.
-
- \subsection{The numerical term} \label{ssec:sort-numerical}
- With the symbolic part of the mixed order treated, it is time to look at the numerical term\footref{foot:numerical-term} which have a symbolic of zero. For this reason it is treated differently than the symbolic terms. The numerical term can be placed either at the beginning or at the end of the mixed order with the values \val{first} and \val{last}, respectively. The package can also determine where to place the numerical term with the value \val{auto}. Compare below
- \begin{align*}
- \text{\inlinecode{sort-numerical=auto:}} &&
- \pdv[order={\beta, 2}, sort-numerical=auto]{f}{x,y} &&
- \pdv[order={\beta, -2}, sort-numerical=auto]{f}{x,y} &&
- \pdv[order={-\beta, 2}, sort-numerical=auto]{f}{x,y} &&
- \pdv[order={-\beta, -2}, sort-numerical=auto]{f}{x,y} \\
- \text{\inlinecode{sort-numerical=first:}} &&
- \pdv[order={\beta, 2}, sort-numerical=first]{f}{x,y} && \pdv[order={\beta, -2}, sort-numerical=first]{f}{x,y} && \pdv[order={-\beta, 2}, sort-numerical=first]{f}{x,y} && \pdv[order={-\beta, -2}, sort-numerical=first]{f}{x,y} \\
- \text{\inlinecode{sort-numerical=last:}} &&
- \pdv[order={\beta, 2}, sort-numerical=last]{f}{x,y} && \pdv[order={\beta, -2}, sort-numerical=last]{f}{x,y} && \pdv[order={-\beta, 2}, sort-numerical=last]{f}{x,y} && \pdv[order={-\beta, -2}, sort-numerical=last]{f}{x,y} \\
- \text{\inlinecode{sort-numerical=symbolic:}} &&
- \pdv[order={\beta, 2}, sort-numerical=symbolic]{f}{x,y} && \pdv[order={\beta, -2}, sort-numerical=symbolic]{f}{x,y} && \pdv[order={-\beta, 2}, sort-numerical=symbolic]{f}{x,y} && \pdv[order={-\beta, -2}, sort-numerical=symbolic]{f}{x,y}
- \end{align*}
- These four options should satisfy every needs.
-
- \subsection{Reversing the sort algorithm} \label{ssec:sort-reverse}
- The reverse keys serves to reverse the ordering of the sorting algorithms. This allows for even greater flexibility over the sorting method. So if the default ordering of an algorithm is not wished it may be reversed with the corresponding reverse key. The reverse keys in action are shown below (\keyval[index=false]{sort-method}{\meta{1 algorithm only}} is also used to better show off the reverse functionality)
- \begin{align*}
- \text{\inlinecode{sort-abs-reverse=false:}} && \pdv[sort-method={abs}, sort-abs-reverse=false, order={2a, -3b}]{f}{x,y} &&
- \text{\inlinecode{sort-abs-reverse=true:}} && \pdv[sort-method={abs}, sort-abs-reverse=true, order={2a, -3b}]{f}{x,y} \\
- \text{\inlinecode{sort-number-reverse=false:}} && \pdv[sort-method={number}, sort-number-reverse=false, order={2a, -3b}]{f}{x,y} &&
- \text{\inlinecode{sort-number-reverse=true:}} && \pdv[sort-method={number}, sort-number-reverse=true, order={2a, -3b}]{f}{x,y} \\
- \text{\inlinecode{sort-sign-reverse=false:}} && \pdv[sort-method={sign}, sort-sign-reverse=false, order={a, -b}]{f}{x,y} &&
- \text{\inlinecode{sort-sign-reverse=true:}} && \pdv[sort-method={sign}, sort-sign-reverse=true, order={a, -b}]{f}{x,y} \\
- \text{\inlinecode{sort-symbol-reverse=false:}} && \pdv[sort-method={symbol}, sort-symbol-reverse=false, order={ab, c}]{f}{x,y} &&
- \text{\inlinecode{sort-symbol-reverse=true:}} && \pdv[sort-method={symbol}, sort-symbol-reverse=true, order={ab, c}]{f}{x,y} \\
- \text{\inlinecode{sort-lexical-reverse=false:}} && \pdv[sort-method={lexical}, sort-lexical-reverse=false, order={a, c, b}]{f}{x,y,z} &&
- \text{\inlinecode{sort-lexical-reverse=true:}} && \pdv[sort-method={lexical}, sort-lexical-reverse=true, order={a, c, b}]{f}{x,y,z} \\
- \end{align*}
-
- \subsection{Mixed order override}
- In cases where the mixed order fails to be calculated or another form is preferred, then the mixed order override can be used
- \begin{example}
- \pdv[order={n+3k, n-k}]{f}{x,y} \\
- \pdv[order={n+3k, n-k}, mixed-order={2(n+k)}]{f}{x,y}
- \end{example}
-
-
+ }{long} +
+ \low{
+ \low{
+ \low[1,2]{4c}{big} +
+ \low[1,1]{3a}{low}
+ }{positive} -
+ \low{
+ \low[1,1]{5d}{big} -
+ \low[2,2]{2b}{low}
+ }{negative}
+ }{short}
+\end{gather*}
+
+In contrast to the previous two examples with three algorithms, this example uses a sorting method with two algorithms: \keyval*{sort-method}{sign,symbol}. The terms are first sorted by sign and then by symbolic length.
+\begin{gather*}
+ \pdv[sort-method = {sign,symbol}, order={3a-3hh-2b, 4c+4gg+2ff, -5d-5ee}]{f}{x,y,z} \\
+ \low{
+ \low{ 4gg + 2ff }{long} +
+ \low{ 3a + 4c }{short}
+ }{positive} -
+ \low{
+ \low{ 3hh - 5ee }{long} -
+ \low{ 2b - 5d }{short}
+ }{negative}
+\end{gather*}
+In the last example, a sorting method with a single algorithm, \keyval{sort-method}{symbol}, is used.
+\begin{gather*}
+ \pdv[sort-method = symbol, order={3a-3hh-2b, 4c+4gg+2ff, -5d-5ee}]{f}{x,y,z} \\
+ \low{ - 3hh + 4gg + 2ff - 5ee }{long} +
+ \low{ 3a - 2b + 4c - 5d }{short}
+\end{gather*}
+
+\subsection{Treating the numerical term} \label{ssec:sort-numerical}
+After handling the symbolic part of the mixed order, we now turn our attention to the numerical term\footref{foot:numerical-term}, which has a symbolic length of zero. For this reason it is treated differently than the symbolic terms. It can be placed either at the beginning or at the end of the mixed order by \val{first} and \val{last}, respectively. Alternatively, it is automatically positioned in the mixed order using \val{auto}. Setting \keyval{sort-numerical}{symbolic}, treats the numerical term as a symbolic term. Its behaviour is determined by the chosen algorithms in \keyval*{sort-method}{\dots}. In this example the sort method is the default value of the package.
+\begin{align*}
+ \text{\inlinecode{sort-numerical=auto:}} &&
+ \pdv[order={\beta, 2}, sort-numerical=auto]{f}{x,y} &&
+ \pdv[order={\beta, -2}, sort-numerical=auto]{f}{x,y} &&
+ \pdv[order={-\beta, 2}, sort-numerical=auto]{f}{x,y} &&
+ \pdv[order={-\beta, -2}, sort-numerical=auto]{f}{x,y} \\
+ \text{\inlinecode{sort-numerical=first:}} &&
+ \pdv[order={\beta, 2}, sort-numerical=first]{f}{x,y} && \pdv[order={\beta, -2}, sort-numerical=first]{f}{x,y} && \pdv[order={-\beta, 2}, sort-numerical=first]{f}{x,y} && \pdv[order={-\beta, -2}, sort-numerical=first]{f}{x,y} \\
+ \text{\inlinecode{sort-numerical=last:}} &&

+The reverse keys serves to reverse the sorting algorithms' ordering, providing more flexibility over the sorting method. If the default ordering of an algorithm is not preferred it may be reversed with the corresponding reverse key. The examples below showcase the reverse functionality. Note that \keyval*[index=false]{sort-method}{1 algorithm only} is also used to better demonstrate the reverse feature, where the algorithm is the one used in the reverse key.

+% the \textsf{interval} package~\cite{INT} with its

%
% \section{Usage}
-% You just have to type intervals in an easy way:
-% |$x\in]0,\pi[\cup]2\pi, 3\pi[$|
-% produce
-% \[ x\in]0, \pi[\cup]2\pi, 3\pi[ \mbox{\quad with \textsf{ibrackets}}, \]
-% instead of
-% \[ x\in\mathclose{]} 0,\pi \mathopen{[}\cup\mathclose{]} 2\pi, 3\pi\mathopen{[}
-% \mbox{\quad without \textsf{ibrackets}}.
-% \]
-%
-% Generally $[$ and $]$ symbols are not defined anymore as delimiters,
-% but as ordinary characters.
-% Thereby a line break could occur between the two square brackets, but
-% it is always possible to transform them
-% into delimiters with |\left| and |\right|.
+% With the \textsf{ibrackets} package, you can easily type intervals. For example the code
+% |$x\in]0,\pi[\cup]2\pi, 3\pi[$| yields
+% \begin{align*}
+% x\in]0, \pi[\cup]2\pi, 3\pi[ &\mbox{\quad with \textsf{ibrackets}}, \\
+% \text{instead of \quad}
+% x\in\mathclose{]} 0,\pi \mathopen{[}\cup\mathclose{]} 2\pi, 3\pi\mathopen{[}
+% &\mbox{\quad without \textsf{ibrackets}}.
+% \end{align*}
+%
+% For the example in the introduction the spacing is now correct with the following simple code:
+% |$x \in ]-\infty, 0]$|, which gives $x \in ]-\infty, 0]$.
%
% \medskip
-% The problem of a sign following the first bracket is solved with this package,
-% so the example in the introduction is simply obtained with |$x \in ]-\infty, 0]$|
-% which gives $x \in ]-\infty, 0]$.
+% In \textsf{ibrackets}, the symbols $[$ and $]$
+% and are not defined by default as delimiters.
+% Therefore, a line break could occur between the two brackets. However,
+% it is always possible to transform them
+% into delimiters using |\left| and |\right|.
%
% \medskip
-% \emph{However, you don't have to leave a space between the first bracket and the sign}: e.g.\@
-% |$x \in ] -\infty, 0]$| yields $x \in ] -\infty, 0]$ with bad spacing around the
-% minus sign.
-% Contrariwise, when you want to write algebra on intervals then
-% \emph{you must leave a blank space between the second bracket and the} +/- \emph{operations},
-% e.g.\@ |$[a, b] + [c, d]$| yields $[a, b] + [c, d]$
-% but |$[a, b]+ [c, d]$| yields $[a, b]+ [c, d]$.
-% To summarize the new behavior of a bracket: it is an ordinary character,
-% but an open delimiter when it is immediately followed by a + or - character.
+% Actually, brackets are set as ``active'' characters,
+% behaving like ordinary characters in most cases.
+% However, when a bracket is \emph{immediately} followed by a + or - character,
+% it becomes an open delimiter. Therefore, when the left bound contains an operator sign,
+% \emph{you don't have to leave a space between the first bracket and the sign},
+% otherwise, the spaces surrounding the operator will be too large.
+% For example if you write |$x \in ] -\infty, 0]$| it yields $x \in ] -\infty, 0]$
+% instead of $x \in ]-\infty, 0]$.
+% Conversely, when dealing with algebraic expressions involving intervals,
+% \emph{you must leave a space between the second bracket and the} +/- \emph{operations}
+% to maintain proper spacing.
+% For instance |$[a, b] + [c, d]$| yields $[a, b] + [c, d]$
+% while |$[a, b]+ [c, d]$| would yield $[a, b]+ [c, d]$.
