MATLAB: How to remove the Paragraph environment generated when publishing an MATLAB file into LaTeX in MATLAB 7.8 (R2009a)

Question

When I publish the following comments in an MATLAB file into LaTeX format:

% This is an example? on displaying comments with LATEX.
% This is the second line.
%
% $$ \sin(\pi x) = 0 $$

MATLAB generates the following LaTeX file:

\begin{par} This is an example? on displaying comments with LATEX. This is the second line. \end{par} \vspace{1em}
\begin{par} $$ \sin(\pi x) = 0 $$ \end{par} \vspace{1em}

I want to remove the Paragraph environment.

Answer 1

MATLAB uses an XSL stylesheet to do the conversion. To remove the Paragraph environment, modify the XSL stylesheet accordingly. For example, see steps below:

1) Execute the following MATLAB commands:

% The directory containing the stylesheet
ssdir = fullfile(matlabroot, 'toolbox', 'matlab', 'codetools', 'private');
% Make a backup of the old stylesheet
copyfile(fullfile(ssdir,'mxdom2latex.xsl'),fullfile(ssdir,'mxdom2latex.xsl.old'))

2) Open 'mxdom2latex.xsl' from 'ssdir' directory in MATLAB:

edit([ssdir filesep 'mxdom2latex.xsl'])

3) Near line 104 in ‘mxdom2latex.xsl’, you will see the following:

<!-- HTML Tags in text sections -->
<xsl:template match="p">\begin{par}
<xsl:apply-templates/><xsl:text>
\end{par} \vspace{1em}
</xsl:text>
</xsl:template>

Remove \begin{par}, \end{par}, and \vspace{1em}:

<xsl:template match="p">
   <xsl:apply-templates/><xsl:text>
</xsl:text>
</xsl:template>

4) Save the changes

5) Publish to LaTeX
