This document is only a simple reference +manual for: +\begin{itemize} +\item Frequent users of the legacy \pkg{physics} package; +\item Those who have to maintain a document written with \pkg{physics}; +\item Users who failed to use \pkg*{unicode-math} with \pkg{physics}. +\end{itemize} +It seems no reason for any other user to read \emph{this} document instead of +the \hyperref{./physics2.pdf}{}{}{package documentation} of \pkg{physics2}, +because this document cannot describe the package in detail. + +In this document, the modules of \pkg{physics2} will be introduced in +the same order as the \pkg{physics} documentation. +\end{abstract} + +\section*{Contents} +\begin{multicols}{2} +\contentsonly +\end{multicols} +\ifnum\value{page}=1 \vfil\clearpage\fi + +\section{Before you start} +\subsection{Legacy problems with \pkg{physics} package} +\label{subsec:physics-legacy-problems} +The \pkg{physics} package provides \cs{qty} command for automatic-sizing +braces. The \cs{qty} command would cause conflict with the \pkg{siunitx} +package, which provides a unified method to typeset numbers and units +correctly. + +Besides, after you loaded \pkg{physics}, when you type \cs{homework} you +will get Maxwell equations and Schrödinger equation. The \cs{homework} +command is ``declared'' in \texttt{physics.sty} but it was not described +in the documentation. That is, if you have defined \cs{homework} before +loading \pkg{physics} package, \pkg{physics} would overwrite the definition +``silently''. + +The vector-notation part of \pkg{physics} uses \pkg*{amsmath}'s (more exactly, +\texttt{amsbsy.sty}'s) \cs{boldsymbol} command to generate bold vectors. +Commands for cross/dot product are defined with \cs{boldsymbol}. +\cs{boldsymbol} uses \cs{mathversion}, a \LaTeXe\ kernel command that works +well with traditional TFM-based fonts but fails when using \pkg{unicode-math}. + +In the definition of \cs{imat}, \cs{xmat}, \cs{dmat} and \cs{admat} commands +from \pkg{physics}, there is a \cs{newtoks} command which allocates a token +list register and two \cs{newcount} commands allocating two count registers. +Every time you write a command like \cs{imat} in your document, then one token +list register and two count registers will be wasted. What's even worse is +that, if you wrote really too many matrix commands from \pkg{physics} (for +example, 32767 \cs{imat}s in \hologo{LuaLaTeX}), there'd be no room for a new +\cs{count}. + +\pkg{physics} integrated all the functions in one file (\texttt{physics.sty}), +that is, you cannot load one of the total seven parts of functions; you have +to load the seven parts altogether, even included the extra \cs{homework} +command we mentioned in the first paragraph. + +Moreover, the code of \texttt{physics.sty} ``abuses'' the \texttt{g}-type +arguments of \pkg*{xparse} package. Therefore the syntax of \pkg{physics} package +looks kind of weird. See \hyperref{https://tex.stackexchange.com/questions/% +470819/macros-dv-and-pdv-eat-the-subsequent-parenthesis-argument/470842#470842}% +{}{}{here} for more. + +\subsection{Loading \pkg{physics2}} +The \pkg{physics2} package includes different modules, among which every module +focuses on one single function. + +Write the following line in the preamble to load \pkg{physics2}: +\begin{Verbatim} +\usepackage{physics2} +\end{Verbatim} +But this is not enough. \pkg{physics2} contains different modules, among which, +only the \modu{common} module would be loaded automatically by the package. +If you want to load other modules of \pkg{physics2}, write this after loading +\pkg{physics2} package: +\begin{displayed} +\cs{usephysicsmodule}\marg{module list} +\end{displayed} +For example, ``\verb|\usephysicsmodule{ab,doubleprod}|'' loads the \modu{ab} +module and the \modu{doubleprod} module. + +You can also load a module with options: +\begin{displayed} +\cs{usephysicsmodule}\oarg{option list}\marg{module} +\end{displayed} +For example, ``\verb|\usephysicsmodule[legacy]{ab}|'' loads \modu{ab} with the +option ``\opt{legacy}''. + +\pardanger Attention, if you used any font package in your document, remember +that \pkg{physics2} requires to be loaded \emph{after} font packages. + + +\section{List of commands} +\subsection{Automatic bracing}\label{subsec:ab-and-legacy} +As mentioned in \S\ref{subsec:physics-legacy-problems}, the \cs{qty} command +from \pkg{physics} would cause conflicts with \pkg{siunitx}. The command for +automatic braces in \pkg{physics2} is \cs{ab}, a shorthand for +{\bfseries a}utomatic {\bfseries b}races. + +The \cs{ab} command requires the \modu{ab} module, so don't forget to write +\verb|\usephysicsmodule{ab}| in the preamble after you loaded \pkg{physics2}. +Always remember, \emph{do not put an \cs{ab} separately in the end of a math +formula}. Take some examples: +\begin{example} +\[ \ab ( \frac12 ) \quad + \ab [ \frac12 ] \quad + \ab\{ \frac12 \} \] +\end{example} +\cs{ab} can modify a delimiter-braced subformula. But the delimiters should +not be out of the range described by the following chart: +\begin{center} +\begin{tabular}{c@{\hskip2em}l@{\hskip2em}c} +\opt{(},\quad\opt{)} && \\ +\opt{[},\quad\opt{]} && \\ +\cs{\{},\quad\cs{\}} &or& \cs{lbrace},\quad\cs{rbrace} \\ +\opt{<},\quad\opt{>} &or& \cs{langle},\quad\cs{rangle} \\ +\opt{|},\quad\opt{|} &or& \cs{vert},\quad\cs{vert} \\ + \cs{|},\quad\cs{|} &or& \cs{Vert},\quad\cs{Vert} +\end{tabular} +\end{center} +For example, \verb|$\ab{foo}$| and \verb|$\ab(foo]$| are illegal, but +\verb|$\ab\{foo\}$| and \verb|$\ab(foo)$| are okay; \verb|$\ab([)$| +is okay but \verb|$\ab(()$| is illegal. + +\pardanger Attention, if you want to delimit a subformula with ``\{'' and +``\}'', you can only write \verb|\{|, \verb|\}| or \cs{lbrace}, \cs{rbrace} +around it. \verb|{| and \verb|}| are not supported in \modu{ab} module. + +Between \cs{ab} and the first delimiter can be a ``biggg'' command, that is, +from \cs{big} to \cs{Bigg}. Actually, you can also write \cs{biggg} and +\cs{Biggg} because \pkg{physics2} defines these after you load it. For example, +\begin{example} +\[ \ab\Big \| \frac12 \| \quad + \ab\Bigg < \frac12 > \quad + \ab\Biggg| \frac12 | \] +\end{example} +Between \cs{ab} and the first delimiter can also be a star (\opt{*}), which +means ``use the default size of delimiters''. But in this situation, you +needn't use the \cs{ab} command at all. + +The \pkg{physics} package provides commands like \cs{pqty}, \cs{bqty}. In +the \modu{ab} module of \pkg{physics2}, these commands have changed to +\cs{pab}, \cs{bab}, etc. The following example shows all the +\texttt{\textbackslash}$X$\texttt{ab} commands in \modu{ab} module: +\begin{example} +\def\0{\frac12} +\[ \pab{\0} \quad \bab{\0} + \quad \Bab{\0} \] +\[ \aab{\0} \quad \vab{\0} + \quad \Vab{\0} \] +\end{example} +Also, after \texttt{\textbackslash}$X$\texttt{ab} can be a ``biggg'' command +or a star. For example, +\begin{example} +\def\0{\frac12} +\[ \pab\Big{\0} \quad \bab*{\0} \] +\end{example} + +\pkg{physics} also provides the following commands: +\begin{Verbatim}[fontsize=\small] +\abs \norm \eval \order \comm \acomm \pb +\end{Verbatim} +\pardanger These commands are not originally supported by \pkg{physics2}, but +the first four commands can be used through the \modu{ab.legacy} module of +\pkg{physics2}: +\begin{Verbatim} +\usephysicsmodule{ab.legacy} +\end{Verbatim} +For example, +\begin{example} +\def\0{\frac12} +\[ \abs{\0} \quad \abs\Big{\0} + \quad \abs*{\0} \] +\end{example} +Users of the legacy \pkg{physics} package should notice that the syntax of +\cs{eval} has been changed to \cs{eval}\oarg{left delimiter}\marg{subformula}. +The \modu{ab.legacy} module abandoned the \verb"\eval(foo|"-like syntax. The +\meta{left delimiter} argument is optional. For example, +\begin{example} +\def\0{\frac12x} +\[ \eval{\0}_a^b \quad + \eval[(]{\0}_a^b \quad + \eval[[]\big{\0}_a^b \] +\end{example} +The \cs{comm}, \cs{acomm} and \cs{pb} (Poisson bracket) are not supported. +But you can write like \verb|\ab[foo,baz]| or \verb|\bab{foo,baz}| instead. + +By the way, you can set the ``order'' symbol in \modu{ab.legacy} through +the \opt{order} option like this: +\begin{Verbatim} +\usephysicsmodule[order=O]{ab.legacy} +\end{Verbatim} +Then \verb|$\order(N)$| yields $O(N)$. + +\subsection{Vector notation} +Unfortunately, there is not a plan for \pkg{physics2} to support this part +of \pkg{physics} completely, but the rest of this section will show some +methods to maintain the document written with \pkg{physics}. + +The \cs{vb}(\opt{*}), \cs{va}(\opt{*}) and \cs{vu}(\opt{*}) are not supported +in any module of \pkg{physics2}. But these commands can be defined by copying +the following lines below and pasting them in the preamble: +\begin{Verbatim}[fontsize=\small] +\makeatletter +\newcommand\vb{\@ifstar\boldsymbol\mathbf} +\newcommand\va[1]{\@ifstar{\vec{#1}}{\vec{\mathrm{#1}}}} +\newcommand\vu[1]{% + \@ifstar{\hat{\boldsymbol{#1}}}{\hat{\mathbf{#1}}}} +\makeatother +\end{Verbatim} +The \cs{boldsymbol} command requires the \pkg*{amsmath} or \pkg*{bm} package. +If you prefer to use \pkg{bm}, you can also use the \cs{bm} command. +What's more, if you tried the commands above, you might find that, +the result of \cs{va} above is different from that of \pkg{physics}. +This is beacuse, if you choose to present a vector in bold, it's alomost +no need to put a \cs{vec} ($\vec{\mskip9mu}$) sign above it. + +However, the method above may not work well with \pkg*{unicode-math} +because there are so many OpenType math fonts without a bold version. +When using \pkg{unicode-math}, it's recommended to use \cs{symbf} and +\cs{symbfit} for a separate vector. For example, \verb|$\symbf{0}$| yields +$\symbf{0}$, and \verb|$\symbfit{A}$| yields $\symbfit{A}$. + +The \cs{vdot} and \cs{cross} commands are not supported in any module +of \pkg{physics2}. Actually, there is no need to use a bold ``$\cdot$'' +or ``$\times$'' for the products of two vectors. Using \cs{cdot} and +\cs{times} is enough. + +The commands related to ``$\nabla$'' are supported through \modu{nabla.legacy} +module. These commands are \cs{grad}, \cs{div} and \cs{curl}. These commands +should not be put in the end of a math formula either (just like \cs{ab}). +Notice that the former \cs{div} command for a ``$\divsymbol$'' (if there +exists one) is redefined as \cs{divsymbol}. For example, +\begin{example} +% \usephysicsmodule{nabla.legacy} +\[ \grad F \quad + \grad(\frac G2) \] +\[ \div\Bigg[X] \quad + \curl*\{\frac Y2\} \] +\[ 2 \divsymbol 1 \] +\end{example} +Actually, the nabla-related commands end with \cs{ab}. Thus, the subformula +after these commands can be delimited with \verb|()|, \verb|[]| and \verb|\{\}|. + +The \modu{nabla.legacy} requires the \pkg*{fixdif} package at least +version 2.0 (file date: 2023/01/31 or after 2023/01/31). + +By the way, if you are used to write \cs{bm} for a vector but interested in +\pkg{unicode-math}, the \modu{bm-um.legacy} module would be a passable +alternative to \pkg{bm} package. Notice that the \cs{bm} command from the +\modu{bm-um.legacy} module can only take \emph{one} letter (or \emph{one} digit) +as its argument. + +\subsection{Operators} +There's no plan for \pkg{physics2} to support this part of \pkg{physics} +completely. The syntax in this part of \pkg{physics} (such as \verb|\tan[2](x)|) +abuses \pkg*{xparse}. + +It's suggested to write like this if you used the \modu{ab} module: +\begin{Verbatim}[fontsize=\small] +$ \sin^2 \ab( \frac{\alpha}{2} ) $ +\end{Verbatim} +Rather than take the superscript as an optional argument of the command of +log-like functions. + +The \pkg{physics} package provides a bundle of commands for log-like functions +that have not been defined in the \LaTeXe\ kernel. Those log-like functions +can be used with the \modu{op.legacy} module; this module do not support +the syntax of \pkg{physics} either. For example: +\begin{example} +% \usephysicsmodule{op.legacy} +\[ \asin^2 x \quad \rank \{ A \} \] +\end{example} +The \cs{Re} and \cs{Im} commands are redefined as operators ``$\Re$'' and +``$\Im$'', while $\Resymbol$ and $\Imsymbol$ are reserved as \cs{Resymbol} and +\cs{Imsymbol}. $\Resymbol$ and $\Imsymbol$ are ordinary symbols but $\Re$ and +$\Im$ are opetators. + +\subsection{Quick quad text}\label{subsec:qtext} +The \modu{qtext.legacy} module provides the \cs{q}\meta{foo} commands +for \cs{quad}-wrapped texts. These commands have the same syntax as +\pkg{physics}. For example, +\begin{example} +% \usephysicsmodule{qtext.legacy} +\[ A \qq {foo bar} B \] +\[ A \qq*{foo bar} B \] +\[ C \qcc D \qcc* E \] +\[ F \qif G \qthen H \] +\end{example} +All the commands described in \S2.4 of +\hyperref{http://mirrors.ctan.org/macros/latex/contrib/physics/physics.pdf}{}{}% +{\textsf{physics} documentation} are supported when using \modu{qtext.legacy} +module, but I don't recommend to use this module unless you are maintaining a +document written with \pkg{physics}'s \cs{q}\meta{foo} commands. + +\subsection{Derivatives} +There is no plan for \pkg{physics2} to support this part of \pkg{physics}. If +you want to typeset the differential operators on a better sense, you can try +the \pkg*{fixdif} package; if you want an easy way to type derivatives, you +can try the \pkg*{derivative} package. These two packages can be used +together. For example, +\begin{example} +% \usepackage{fixdif,derivative} +\[ \pdv{f}{x,y,z} \d x \] +Math ($\d x$) v.s.\ Text (\d x) +\end{example} +Here are the documentations of +\hyperref{http://mirrors.ctan.org/macros/latex/contrib/fixdif/fixdif.pdf}% +{}{}{\textsf{fixdif}} and +\hyperref{http://mirrors.ctan.org/macros/latex/contrib/derivative/derivative% +.pdf}{}{}{\textsf{derivative}}. + +\pkg{fixdif}'s commands behave better in superscripts and subscripts. + +\subsection{Dirac bra-ket notation} +There are two solutions to Dirac bra-ket in \pkg{physics2} --- \modu{ab.braket} +and \modu{braket}. These two modules are \emph{not} compatible and neither of +them supports \pkg{physics}'s syntax completely. +Click \hyperlink{para:ab.braket}{\textcolor{cyan}{here}} to see the +\modu{ab.braket} module and \hyperlink{para:braket}{\textcolor{cyan}{here}} +to see the \modu{braket} module. + +\paragraph{The \modu{ab.braket} module} +\hypertarget{para:ab.braket}{This} module provides four commands --- \cs{bra}, \cs{ket}, \cs{braket} and +\cs{ketbra}.

If you never used \pkg{physics} package +before, just read \emph{this} documentation. +\end{abstract} + +\tableofcontents + +\section{Introduction} +\subsection{The purpose of this package} +This package aims to provide a bundle of commands for typesetting math faster +in different modules. The commands provided by \pkg{physics2} and its different +modules are designed to be short and easy to memorize. + +\subsection{Packages required} +The \pkg{physics2} package itself only requires the \pkg*{keyval} package, which +is part of the \pkg*{latex-graphics} bundle. Almost every \LaTeX\ distribution +will include this bundle. + +Different modules of \pkg{physics2} might require different packages. It will +be explained in the following sections that which module requires which package. + +The \pkg{physics2} package requires \LaTeXe\ kernel released after 2020/10. +Please make sure that your \LaTeX\ distribution is not too old. + +\subsection{Loading the \pkg{physics2} package} +Just like loading any package, write +\begin{Verbatim} +\usepackage{physics2} +\end{Verbatim} +in the preamble to load the \pkg{physics2} package. In this version, +\pkg{physics2} doesn't provide a package option. + +However, \pkg{physics2} itself only provides very few functions. Actually, it +just provides a method to load modules. You need to load different modules of +\pkg{physics2} to have different kinds of functions applied to your document. + +\subsection{Loading a module of \pkg{physics2}} +You can load a module of \pkg{physics2} only \emph{after} you write +\verb|\usepackage{physics2}| in the preamble. Load a \pkg{physics2} module +like this: +\begin{center} +\cs{usephysicsmodule}\marg{module} +\end{center} +The usage of \cs{usephysicsmodule} is similar to \cs{usepackage}, so you can +load more than one modules in one line. For example, +\begin{Verbatim} +\usephysicsmodule{ab,ab.braket} +\end{Verbatim} +This line loads the \modu{ab} and \modu{ab.braket} modules. + +You can also load \emph{one} module with options. The options of a +\pkg{physics2} module can be a comma-separated key-value list. For example, +\begin{Verbatim} +\usephysicsmodule[tightbraces=true]{ab} +\usephysicsmodule{ab.braket,doubleprod} +\end{Verbatim} +These two lines load the \modu{ab} module with option +\opt{tightbraces\:=\:true} and load \modu{ab.braket} and \modu{doubleprod} +modules. + +\pardanger +The \modu{common} module will be loaded automatically when you load the +\pkg{physics2} package and \emph{only} the \modu{common} module will be +loaded automatically. Any other module should be loaded manually by writing +\cs{usephysicsmodule}\marg{module} after you loaded \pkg{physics2} in the +preamble. + +The following sections introduce all the user-level modules of \pkg{physics2}. +View back to the table of contents to see the names of user-level modules. + +\section{Modules of \pkg{physics2}} +\subsection{The automatically loaded \modu{common} module} +The \modu{common} module provides the following commands: + +\cs{delopen} and \cs{delclose}, followed by a math delimiter. They can be +regarded as abbreviations of ``open delimiter'' and ``close delimiter''. If +you had heard of the \pkg*{mleftright} package. You can regard \cs{delopen} +and \cs{delclose} as a simpler version of \cs{mleft} and \cs{mright}. +For example, +\begin{example} +\[ 0 \left(\frac12\right) 3 \] +\[ 0 \delopen(\frac12\delclose) 3 \] +\end{example} + +\cs{biggg} and \cs{Biggg}, followed by a math delimiter. They are even bigger +than \cs{Bigg}. \cs{biggg} and \cs{Biggg} may be useful when you need to write +something really tall in math mode, but most OpenType math font do not support +\cs{langle} (or U+27E8) and \cs{rangle} (or U+27E9) in this large size. Take +an example, +\begin{example} +\[\Biggg(\biggg(\Bigg(\bigg(\Big(\big(( +)\big)\Big)\bigg)\Bigg)\biggg)\Biggg)\] +\end{example} +\cs{bigggl}, \cs{bigggm}, \cs{bigggr}, \cs{Bigggl}, \cs{Bigggm} and \cs{Bigggr} +are also supported. + +\subsection{The \modu{ab} module --- automatic braces} +This module provides the command \cs{ab}. The \cs{ab} command, as a shorthand +of ``automatic braces'', would specify the size of the following pair of +delimiters. The delimiters after \cs{ab} should not be out of the range +described by the following chart: +\begin{center} +\begin{tabular}{c@{\hskip2em}l@{\hskip2em}c} +\opt{(},\quad\opt{)} && \\ +\opt{[},\quad\opt{]} && \\ +\cs{\{},\quad\cs{\}} &or& \cs{lbrace},\quad\cs{rbrace} \\ +\opt{<},\quad\opt{>} &or& \cs{langle},\quad\cs{rangle} \\ +\opt{|},\quad\opt{|} &or& \cs{vert},\quad\cs{vert} \\ + \cs{|},\quad\cs{|} &or& \cs{Vert},\quad\cs{Vert} +\end{tabular} +\end{center} +For example, it's illegal to write an ``\verb|\ab(|'' without a ``\verb|)|''; +it's also illegal to write \verb|\ab=foo=|. Take some correct examples: +\begin{example} +\[ \ab ( \frac12 ) \quad + \ab [ \frac12 ] \quad + \ab\{ \frac12 \} \] +\end{example} +You can also write a command from \cs{big} to \cs{Biggg} between \cs{ab} +and the first delimiter, which means to specify the size of delimiters manually. +Also, you can write a star (\opt{*}) between \cs{ab} and the first delimiter, +to prevent \cs{ab} from setting the size of delimiters. For example, +\begin{example} +\[ \ab <\frac12> \quad + \ab\biggg|\frac12| \quad + \ab* \|\frac12\| \] +\end{example} +\pardanger +Always remember, do not put an \cs{ab} separately at the end of math mode like +\verb|$\ab$|, because \cs{ab} will try to absorb the following math shift +character (\verb|$|) as its argument. + +The \modu{ab} module also provides \texttt{\textbackslash}$X$\texttt{ab} +commands, where $X$ can be \opt{p}, \opt{b}, \opt{B}, \opt{a}, \opt{v} and +\opt{V}. These commands take a normal argument but not an argument delimited +with paired delimiters. For example, +\begin{example} +\def\0{\frac12} +\[ \pab{\0} \bab{\0} \Bab{\0} \] +\[ \aab{\0} \vab{\0} \Vab{\0} \] +\end{example} +After \texttt{\textbackslash}$X$\texttt{ab} can be a ``biggg'' command or a +star. For example, +\begin{example} +\def\0{\frac12} +\[ \pab\Big{\0} \quad \bab*{\0} \] +\end{example} + +\paragraph{The options of \modu{ab} module} +\opt{tightbraces}, a bool type key, whose default value is \opt{true}, +influences whether thin skips are reserved around the paired delimiters. +It only works with the automatically sized delimiters. + +\subsection{The \modu{ab.braket} module --- Dirac bra-ket notation} +This module provides four commands --- \cs{bra}, \cs{ket}, \cs{braket} and +\cs{ketbra}. After these commands can be a star (\opt{*}) or a ``biggg'' +command. These commands share similar syntaxes like \cs{ab}'s syntax. But, +\emph{the bra-ket commands from \modu{ab.braket} module are completely different +from \cs{ab}}.

It is quite different from \verb|\mathrel{>}| or +\verb|\mathrel{<}| because in these commands' argument, \opt{>} and \opt{<} +will be redefined. + +Next, the \modu{braket} module will be introduced.

The entries should +be separated by commas. The \opt{empty} option is optional, with default value +\opt{0}. For example, +\begin{example} +\[ + \diagmat { 1, 2, 3 } +\] +\end{example} +\cs{pdiagmat}, \cs{bdiagmat}, \cs{Bdiagmat}, \cs{vdiagmat} and \cs{Vdiagmat} +are also available. Prefixes like \opt{p}, \opt{b}, \opt{B} have the same +meaning as the \opt{p}, \opt{b}, \opt{B} in \pkg{amsmath}'s \opt{pmatrix}, +\opt{bmatrix} and \opt{Bmatrix}. For example, +\begin{example} +\[ + \pdiagmat [ empty = {} ] + { a, b, c, d } +\] +\end{example} +This module requires \pkg{amsmath}. + +\paragraph{The options of \modu{diagmat} module} +You can set the default value of \cs{diagmat}'s empty entries in the module +option like this: +\begin{Verbatim} +\usephysicsmodule[empty={\cdot}]{diagmat} +\end{Verbatim} + +\subsection{The \modu{doubleprod} module --- tensors' double product operator} +Take an example of this module: +\begin{example} +$ A \doublecross B \doubledot C $ +\end{example} +\cs{doublecross} and \cs{doubledot} are regarded as binary operators by \TeX. + +\paragraph{The options of \modu{doubleprod} module} +You can control the scale of ``$\times$'' and ``$\cdot$'' in \cs{doublecross} +and \cs{doubledot} in module option. For example, +\begin{Verbatim} +\usephysicsmodule[crossscale=0.75,dotscale=1.2]{doubleprod} +\end{Verbatim} +The default values of \opt{crossscale} and \opt{dotscale} are \opt{0.8} and +\opt{1}.

For example, +\begin{example} +\[ + \pxmat{M}{3}{3} +\] +\end{example} +If \meta{rows shown} and \meta{cols shown} contain non-digit characters, +extra dots will be added. For example, +\begin{example} +\[ + \bxmat[showleft=3,showtop=2] + {X}{m}{n} +\] +\end{example} +In this example we used the \opt{showleft} and \opt{showtop} options. The +default value of them is the value of \opt{MaxMatrixCols} minus 2. You can +also set them in the module option like this: +\begin{Verbatim} +\usephysicsmodule[showtop=3,showleft=3]{xmat} +\end{Verbatim} +Then every \cs{xmat} with non-digital \meta{rows shown} and \meta{cols shown} +will have 2 top-most rows and 3 left-most columns shown. This will also +influence ``\cs{xmat}''s with digital \meta{rows shown} and \meta{cols shown} +when \meta{rows shown} and \meta{cols shown} are larger than the values +corresponding to \opt{showtop} and \opt{showleft}. For example, +\begin{example} +% \usephysicsmodule +% [showtop=3,showleft=3]{xmat} +\[ \pxmat{A}{8}{8} \] +\end{example} +However, when \meta{rows shown} and \meta{cols shown} are 1 greater than +\meta{showtop} and \meta{showleft}, for example, \meta{rows shown}$\:=4$ and +\meta{cols shown}$\:=4$ in last example's settings, \cs{xmat} will still add +the extra dots: +\begin{example} +% \usephysicsmodule +% [showtop=3,showleft=3]{xmat} +\[ \pxmat{A}{4}{4} \] +\end{example} +In such situations, we need to specify \opt{showtop} and \opt{showleft} +manually. For example, +\begin{example} +% \usephysicsmodule +% [showtop=3,showleft=3]{xmat} +\[ \pxmat[showtop=4,showleft=4] + {A}{4}{4} \] +\end{example} + +The \cs{xmat} command provides the \opt{format} option, which allows users +to use a new entry format. For example, +\begin{example} +\[ + \xmat [showleft=2,showtop=2, + format=\texttt{#1[#2][#3]}] + {x}{m}{n} +\] +\end{example} +In the value of \opt{format} key, \verb|#1| stands for the common entry, +or the first mandotary \meta{entry} argument of \cs{xmat}; \verb|#2| +stands for the row index and \verb|#3| stands for the column index. + +This module requires \pkg{amsmath}. + +\paragraph{The options of \modu{xmat} module} +Only \opt{showtop} and \opt{showleft} can be used as module options. +\opt{format} should be only used in the optional argument of the +\cs{xmat} command. + +\section{The ``legacy'' modules} +The legacy modules have similar names like \meta{module}\opt{.legacy}. Most of +them are designed to provide solutions to maintain documents written with the +legacy \pkg{physics} package. It's not suggest to use them in a new document. + +\subsection{The \modu{ab.legacy} module} +This module provides the following commands: +\begin{Verbatim}[fontsize=\small] +\abs \norm \eval \order +\end{Verbatim} +They can take a normal argument. Between these commands and their argument +can be a ``biggg'' command or a star. For example, +\begin{example} +\def\0{\frac12} +\[ \abs{\0} \quad + \norm\Big{\0} \quad + \order*{\0} \] +\end{example} +\begin{example} +\def\0{\frac12x} +\[ \eval{\0}_a^b \quad + \eval[(]{\0}_a^b \quad + \eval[[]\big{\0}_a^b \] +\end{example} +You can set the ``order'' symbol in this module through +the \opt{order} option like this: +\begin{Verbatim} +\usephysicsmodule[order=O]{ab.legacy} +\end{Verbatim} +For further information of this module, see \S\ref*{lega-subsec:ab-and-legacy} +of \hyperref{./physics2-legacy.pdf}{}{}{physics2-legacy}. + +\subsection{The \modu{bm-um.legacy} module} +If you are maintaining a document with plenty of ``\cs{bm}''s or +``\cs{boldsymbol}''s in it but want to use \pkg{unicode-math} package +simultaneously, you could take a look at this module. + +The \cs{bm} command from \pkg{bm} package uses \cs{mathversion} to support +its function, but there are few OpenType math fonts who released with a bold +version. The \modu{bm-um.legacy} module provides a \cs{bm} command too, but +this \cs{bm} can only take \emph{one} math character or a series of math +characters sharing the same category code as its argument. +If the argument was Latin letters or Greek letters, \cs{bm} would switch to +the bold italic glyphs corresponding to them (if there exists bold italic +glyphs); else \cs{bm} would switch to the bold upright glyphs. For example, +\begin{example} +$\bm{0}\bm{A}\bm{z} + \bm{\alpha}\bm{\Omega}$ +\end{example} + +\subsection{The \modu{nabla.legacy} module} +This module provides some commands related to nabla ($\nabla$). Notice that +this module requires the \pkg{fixdif} package with file date 2023/01/31 at +minimum. + +This module defines \cs{grad} and \cs{curl} and redefines \cs{div}. For example, +\begin{example} +\[ \grad V \] +\[ \div (x,y,z) \] +\[ \curl(x,y,z) \] +\end{example} +The ``$\divsymbol$'' symbol was redefined as \cs{divsymbol}. + +\subsection{The \modu{op.legacy} module} +This module provides a series of commands for log-like operators. They are +\begin{Verbatim} +\asin \acos \atan +\acsc \asec \acot +\Tr \tr \rank +\erf \Res \res +\PV \pv +\Re \Im +\end{Verbatim} +where \cs{Re} and \cs{Im} are redefined. The first four lines of commands +yield what they look like in math mode. For example, +\begin{example} +$\asin x$ \quad $\rank A$ +\end{example} +\cs{PV} yields ``$\PV$'' as an ordinary symbol and \cs{pv} yields ``$\pv$''. +For example, +\begin{example} +$\PV f(z)$ \quad $\pv f(z)$ +\end{example} +\cs{Re} and \cs{Im} are redefined as ``$\Re$'' and ``$\Im$''. $\Resymbol$ +and $\Imsymbol$ are redefined as \cs{Resymbol} and \cs{Imsymbol}, in default. + +This module \emph{does not} require \pkg{amsmath}. + +\paragraph{The options of \modu{op.legacy} module} +\opt{ReIm}, a bool key with default value \opt{true}, determines whether to +redefine \cs{Re} and \cs{Im}. If you want to reserve the definition of +\cs{Re} and \cs{Im}, you can write like this: +\begin{Verbatim} +\usephysicsmodule[ReIm=false]{op.legacy} +\end{Verbatim} + +\subsection{The \modu{qtext.legacy} module} +This module was written just to offer a method to maintain documents written +with the legacy \pkg{physics} package. See \S\ref*{lega-subsec:qtext} of +\hyperref{./physics2-legacy.pdf}{}{}{physics2-legacy} for more information. + +\end{document} \ No newline at end of file diff --git
