+# Introduction
+The lualinalg package is developed to perform operations on vectors and matrices defined over the field of real or complex numbers inside LaTeX documents.
+It provides flexible ways for defining and displaying vectors and matrices.
+No particular environment of LaTeX is required to use commands in the package.
+The package is written in Lua, and tex file is to be compiled with the LuaLaTeX engine.
+The time required for calculations is not an issue while compiling with LuaLaTeX.
+There is no need to install Lua on the user's system as TeX distributions (TeXLive or MikTeX) come bundled with LuaLaTeX.
+It may also save users' efforts to copy vectors and matrices from other software (which may not be in latex-compatible format) and to use them in a tex file.
+The vectors and matrices of reasonable size can be handled with ease.
+The package can be modified or extended by writing custom Lua programs.
+
+# License
+The \verb|lualinalg| package is released under the LaTeX Project Public License v1.3c or later.
+The complete license text is available at \url{http://www.latex-project.org/lppl.txt}.
+It is developed in Lua. Lua is available as a certified open-source software.
+Its license is simple and liberal, which is compatible with GPL.
+The package makes use of \verb|complex.lua| file which is available on \url{https://github.com/davidm/lua-matrix/blob/master/lua/matrix.lua}.
+It is available under the same licensing as that of Lua.
+The package also loads the luamaths package, which is available under the LaTeX Project Public License v1.3c or later.
+This package is loaded to use the standard mathematical functions and for computations on real numbers while performing operations on vectors and matrices.
+
+#Installation and Inclusion
+The installation of lualinalg package is similar to plain latex package, where the .sty file is in LaTeX directory of texmf tree.
+The package can be included with \usepackage{lualinalg} command in the preamble of the LaTeX document. \ No newline at end of file

+\section{Introduction}
+
+The \verb|lualinalg| package is developed to perform operations on vectors and matrices defined over the field of real or complex numbers inside LaTeX documents. It provides flexible ways for defining and displaying vectors and matrices. No particular environment of LaTeX is required to use commands in the package. The package is written in Lua, and tex file is to be compiled with the LuaLaTeX engine. The time required for calculations is not an issue while compiling with LuaLaTeX. There is no need to install Lua on the user's system as TeX distributions (TeXLive or MikTeX) come bundled with LuaLaTeX. It may also save users' efforts to copy vectors and matrices from other software (which may not be in latex-compatible format) and to use them in a tex file. The vectors and matrices of reasonable size can be handled with ease. The package can be modified or extended by writing custom Lua programs (Section \ref{customuse}).

+The installation of the \verb|lualinalg| package is similar to the plain latex package, where the \verb|.sty| file is in the LaTeX directory of the texmf tree. The package can be included with \verb|\usepackage{lualinalg}| command in the preamble of the LaTeX document.
+
+The \verb|lualinalg| package is released under the LaTeX Project Public License v1.3c or later. The complete license text is available at \url{http://www.latex-project.org/lppl.txt}. It is developed in Lua. Lua is available as a certified open-source software. Its license is simple and liberal, which is compatible with GPL. The package makes use of \verb|complex.lua| file which is available on \url{https://github.com/davidm/lua-matrix/blob/master/lua/matrix.lua}. It is available under the same licensing as that of Lua. The package also loads the \href{https://ctan.org/pkg/luamaths}{luamaths} package, which is available under the LaTeX Project Public License v1.3c or later. This package is loaded to use the standard mathematical functions and for computations on real numbers while performing operations on vectors and matrices.
+\section{Defining vectors and performing operations on vectors}
+\subsection{Defining Vectors} Vectors are defined with the \verb|\vectornew| command.
+\begin{verbatim}
+\vectorNew{vector name}{coordinates}
+\end{verbatim}
+ This command has two compulsory arguments: \verb|vector name| and \verb|coordinates|. Coordinates of vectors are enclosed in curly braces. A comma separates coordinates. The complex numbers are to be enclosed in single or double quotes inside the \verb|complex()| function. The following are a few valid ways of defining vectors.
+\begin{lstlisting}
+\vectorNew{v1}{{1,2,3,4,5,6}}
+\vectorNew{v2}{{3,6,complex('6+6i')}}
+\end{lstlisting}
+The standard vector of dimension \(n \) with \(i^{th}\) coordinate \(1\) can be produced by using the following command.
+\begin{lstlisting}
+\vectorNew{e}{n,'e',i}
+\end{lstlisting}
+For example, the following commands
+\begin{lstlisting}
+\vectorNew{e_1}{3,'e',1}
+\(e_1=\left(\vectorPrint{e}\right)\)
+\end{lstlisting}
+output to \(e_1 = \left(1.0,0.0,0.0\right) \).

+\section{Known issues and limitations}
+\begin{itemize}
+\item The package supports small and big numbers. They can be input in the usual scientific notation. The math library in Lua defines constants with the maximum \verb|math.maxinteger| and the minimum \verb|math.mininteger| values for an integer. The result wraps around when there is a computational operation on integers that would result in a value smaller than the \verb|mininteger| or larger than the \verb|maxinteger|. It means that the computed result is the only number between the \verb|miniinteger| and \verb|maxinteger|.
+
+\item The package currently supports only numerical computations. The table in a Lua is a data type that implements an associative array. This feature is used in packages to define and store vectors and matrices. This approach is close to object-oriented programming. It will allow easy conversion of algorithms in packages for symbolic computations. Future package updates will consider algorithm conversions to support symbolic calculations.
+
+\item The error handling mechanism in the tool is not robust. There are some custom errors included in the package. However the package mostly depends on error handling mechanism of Lua. The error handling can be strengthened in future updates of the package.

+\secc[namespaces] Concept of namespaces of control sequences
-All control sequences used in \OpTeX/ are used and defined with `_` prefix.
-The user can be sure that when he/she does `\def\foo` then neither internal macros of
-\OpTeX/ nor \TeX/ primitives will be damaged. For example
-`\def\if{...}` will not damage macros because \OpTeX/'s macros
-are using `\_if` instead of `\if`.
+\OpTeX/ sets the category code of the \"`_`" character to 11 (letter)
+and it is never changed.\fnote
+{This is only singular exception form category codes given by plain \TeX.}
+So, we can always construct multiletter control sequence names from letters
+`A`--`Z`, `a`--`z`, and `_`. The \"letter `_`" works in math mode as a subscript
+constructor because it is set as math active character (see section~\ref[math-macros]).
-All \TeX/ primitives are initialized with two representative control
-sequences: `\word` and `\_word`, for example `\hbox` and `\_hbox`.
-The first alternative is reserved for users or such control sequences
-can be re-defined by a user.
-
-\OpTeX/ sets the character `_` as letter, so it can be used in
-control sequences. When a control sequence begins with this character
-then it means that it is a primitive or it is used in \OpTeX/ macros as
-internal. User can redefine such prefixed control sequence only
-if he/she explicitly knows what happens.
-
-We never change catcode of `_`, so internal macros can be
-redefined by user without problems if it is desired. We don't need

-\OpTeX/ defines all new macros as prefixed. For public usage of such macros,
-we need to set their non-prefixed versions. This is done by
+We distinguish following namespaces for multiletter control sequences:
+\begitems
+* Only alphabetical names are in the {\em public namespace}. They are intended
+ for end users when creating a document. Sometimes it is called {\em user
+ namespace} too. For example `\hbox`, `\fontfam`, `\MyMacro`.
+* Only alphabetical lowercase names prefixed by single \"`_`" are in the
+ {\em private namespace}. It is used in \OpTeX/ internal macros.
+ For example `\_hbox`, `\_fontsel`.
+* Names in the form `\_<pkg>_<name>` are in the {\em package namespace},
+ see section~\ref[pkg-namespace]. For example `\_qr_size`, `\_math_alist`.
+* Names starting with two \"`_`" are in the {\em reserved namespace}. They can be
+ used for internal control sequences in font family files or in similar cases.
+* Other names which include \"`_`" but not as the first character can be used
+ too, but with care, see the end of this section.
+\enditems
+All \TeX/ primitives are initialized with two control sequences with the
+same meaning: {\em prefixed} control sequence
+(in private namespace, for example `\_hbox`)
+and {\em unprefixed} control sequence (in public namespace, for example `\hbox`).
+All \OpTeX/ macros intended for end users are initialized in these two forms
+too, for example `\_ref` and `\ref`.
+
+Users can declare any control sequences in the public namespace without worrying
+that \OpTeX/ behavior is changed. This is because \OpTeX/ uses exclusively
+prefixed control sequences in its macros. For example, a user can declare
+`\def\fi{finito}` and nothing bad happens, if the user doesn't use `\fi` in
+its original primitive meaning. You don't have to know all \TeX/ primitives
+and \OpTeX/ macros, you can declare control sequences for your use in the
+public namespace without limitations and nothing bad will happen.
+
+You can use control sequences from private or package namespace in
+a \"read-only manner" without changing \OpTeX/ behavior too.
+On the other hand, if you re-define a control sequence in the private name
+space, the \OpTeX/ behavior can be changed. You can do it
+but we suppose that you know what you are doing and what \OpTeX/
+behavior is changed.
+
+All multiletter control sequences declared by \OpTeX/ are defined in the private
+namespace first (`\_def\_macro{...}`). If the declared control sequences are
+intended for end users too then they are exported to the public namespace
+after that. It is done by the \^`\public` macro:

I hate the \^`\frac`, \^`\dfrac` and \^`\tfrac` macros defined in \LaTeX/
but someone may want to use them. This package defines them.
But I note: usage of `$1\over2$` for $1\over2$
is much more understandable than \LaTeX's `$\frac12$`.
-The vectors and matrices are ususally printed by `{\bf A}{\bf x}`.
+The vectors and matrices are usually printed by `{\bf A}{\bf x}`.
The package provides a shortcut `\.<letter>` to do the same, so user can write
`\.A\.x` for multiplication of a matrix $\.A$ by a vector $\.x$.
We strictly don't recommend usage of `\.`, `\v`, `\=`, etc.\ for accents, so
`math.opm` can define `\.` differently than the classical meaning \"dotaccent".
+
+\sec System of equations printed by `\eqsystem`
+
+The \^`\eqsystem``{<equations>}` enables to write systems of equations more
+comfortably. The equations are separated by `\cr` and the aligned columns
+are separated by space. For example:
+\begtt
+$$
+ \eqsystem{ x + y - 2z = 10 \cr
+ 2x - 7y + z = 13 \cr
+ -x + y ~ ~ = -5 }
+$$
+\endtt
+prints
+$$
+ \eqsystem{ x + y - 2z = 10 \cr
+ 2x - 7y + z = 13 \cr
+ -x + y ~ ~ = -5 }
+$$
+Note that empty columns have to be filled by `~` mark.
+There are columns for variables (possibly multiplied by a constant) and for
+binary operators `+` and `-` or relations `=`, `>` etc. or constants. Each column
+is aligned to right. The number of columns is unlimited (we have 7 columns in
+the example above). All given equations are packed to the `\vcenter` box.
+
+The spaces between lines are enlarged by the value of \^`\eqskip`
+and the horizontal spaces between columns are enlaged by \^`\eqsep`.
+Both registers are set to 0\,pt by default.
+
+The \^`\eqfil` register is \"left filler" applied to each item in the \^`\eqsystem` columns.
+Its default is `\eqfil={\hfill}`. The right filler is hardwired and it is `\hfil`.
+This makes columns aligned to right by default. For example, when you set
+`\eqfil={\hfil}` then you have columns centered.
+
+The \^`\eqsystem` macro allows optional parameter which is processed inside
+group before printing equations. You can do local settings here, for example
+`\eqsystem[\eqskip=2pt \eqsep=5pt]{...}`.

-\sec Variables and digits from currently used text font
+\sec `\bf` and `\bi` can do shapes with serifs
+
+\OpTeX/ sets `\bf` and `\bi` math selectors as sans serif, because this
+follows the old traditional math typesetting of vectors and matrices.
+But Knuth's \TeX/ has another default behavior:`\bf` and `\bi` select serifed
+shaped. So, many people consider it as a standard. You can declare \^`\bfserif` if
+you want serifed `\bf` and `\bi` math letters.
+
+\sec[rmchars] Selected upright letters and variants for Greek letters
+
+Some mathematicians claim that the letters $e$, $i$ and $\pi$ in meaning
+\"a constant" should be printed in upright form. \TeX/ prints all variables in
+math italic, but this package enables to set exceptions for some letters.
+For example after \^`\rmchars``{e, i, \pi}`, all occurrences of these three letters
+in math mode will be set in upright shape. If you set this, then the
+well-known math identity `$e^{i\pi}=-1$` looks like this:
+$$
+ {\rm e}^{\rm i\muppi} = -1, \qquad \hbox{compare with:}\quad e^{i\pi} = -1.
+$$
+The syntax is \^`\rmchars``{<list>}`, where <list> is a list of characters
+separated by (optional) commas. The character is `a` to `z` or `A` to `Z` or
+`\alpha` to `\omega`.
+
+If you set a character by `\rmchars` globally and you want to print it in italic
+locally then use `\mit`, for example `{\mit e}` prints $e$.
+
+Several Greek letters have their variant shape:
+`\epsilon`~$\epsilon$, `\varepsilon`~$\varepsilon$,
+`\sigma`~$\sigma$, `\varsigma`~$\varsigma$,
+`\phi`~$\phi$, `\varphi`~$\varphi$,
+`\theta`~$\theta$, `\vartheta`~$\vartheta$,
+`\pi`~$\pi$, `\varpi`~$\varpi$,
+`\kappa`~$\kappa$, `\varkappa`~$\varkappa$,
+`\rho`~$\rho$, `\varrho`~$\varrho$,
+`\Theta`~$\Theta$, `\varTheta`~$\varTheta$.
+Maybe, there is a tradition of usage variant shapes instead of standard ones
+in your mathematics field. Then you can use
+\^`\vargreek``{<list>}`, where <list> includes the list of no-var control
+sequences for these letters (separated by optional comma).
+For example `\vargreek{\epsilon \phi \rho}` causes that `\epsilon` is
+printed as $\varepsilon$, `\phi` as $\varphi$ and `\rho` as $\varrho$.
+
+If you want to declare a Greek letter by both `\vargreek` and `\rmchars`,
+use `\rmchars` first.
+
+The package provides two options `rmchars` and `vargreek`. The equation
+sign must follow and then the `{<list>}` with syntax mentioned above. For example
+`\mathset{vargreek={\epsilon,\rho}}`.
