    \begin{document}
        Here we have a nice matrix:
        \[
            \eqA{}
        \]

    \end{document}

How can I add horizontal and vertical lines and label column and rows of the table. The contents of the table should be updated every time by input eqA.
please see image enter image description here

Best Answer

You can use \hline between the rows to get horizontal lines and | in the array preamble to specify vertical lines. As (again) you have not posted an example that may be run locally I haven't shown the result of adding these.

\begin{array}{|c|c|}
\hline
a&b\\
\hline
x&y\\
\hline
\end{array}

is a 2x2 example with horizontal and vertical rules.

[Tex/LaTex] Use column-separator & (ampersand) inside \newenvironment

The problem is that the \begin{...} and \end{...} pair commands automatically create a "group" so that, in effect, the & and \\ are "out of scope" for the tabular, while inside the "production" environment they just show up at a place where the compiler is not expecting them.

A second problem with your definitions is that, even if they would work, they would be adding an extra \\ at the end of the tabular, adding an unwanted space at the end. Perhaps some more appropriate definitions would be

\documentclass[a4paper,10pt]{article}

\newcommand{\production}[1]{#1 ::= &}
\newenvironment{grammar}{\tabular{p{3cm}l}}{\endtabular}

\begin{document}
\begin{grammar}
\production{XmlStartTag} ... \\
\production{XmlOtherTag} ... \\
\production{XmlEndTag} ...
\end{grammar}
\end{document}

Note no \\ at the end of the last production. Also in the definition of the grammar you don't need to repeat the work of \begin/\end, and you can instead directly use \tabular and \endtabular.

[Tex/LaTex] Changing fraction style in LaTeX as generated by Matlab

If you want the matrix to be displayed with decimal values, you could simply redefine the \frac{}{} macro to produce the decimal result for you.

All you need to do is to call \ConverFracToDecimal and you will get the first result below. Without using \ConverFracToDecimal you obtain the second result:

Notes:

The fp package was used for the computation.
The siunitx package was used to round and format the decimal digits. See How to set the precision in numbers for more options.

Code:

\documentclass{article}
\usepackage{fp}
\usepackage{siunitx}

\newcommand{\ConverFracToDecimal}{%
    \renewcommand*{\frac}[2]{%
        \FPdiv\Result{##1}{##2}%
        \num[round-mode=places,round-precision=4]{\Result}%
    }%
