\section*{Usage --- 3 ways}
1) This inline demo \mcode{for i=1:3, disp('cool'); end;} uses the \verb|\mcode{}| command.\footnote{Works also in footnotes: \mcodefn{for i=1:3, disp('cool'); end;}}
2) The following is a block using the \verb|lstlisting| environment.
\begin{lstlisting}
for i = 1:3
if i >= 5 % literate programming replacement
disp('cool'); % comment with some §\mcommentfont\LaTeX in it: $\mcommentfont\pi x^2$§
end
[~,ind] = max(vec);
x_last = x(1,end);
v(end);
really really long really really long really really long really really long really really long line % blaaaaaaaa
end
\end{lstlisting}
Note: Here, the package was loaded with the \verb|framed|, \verb|numbered|, \verb|autolinebreaks| and \verb|useliterate| options. \textbf{Please see the top of mcode.sty for a detailed explanation of these options.}
3) Finally, you can also directly include an external m-file from somewhere on your hard drive (the very code you use in \textsc{Matlab}, if you want) using the \verb|\lstinputlisting{/SOME/PATH/FILENAME.M}| command. If you only want to include certain lines from that file (for instance to skip a header), you can use \verb|\lstinputlisting[firstline=6, lastline=15]{/SOME/PATH/FILENAME.M}|.

All that this package does is to configure the \verb|listings| package for you. If anything is not working the way you want it, refer to the \verb|listings| documentation first and / or take a look at the \verb|mcode.sty| file itself, which is well documented internally.\\
The \verb|listings| documentation can be accessed either by typing \verb|texdoc listings| into a command prompt on your system, or online:\\\scriptsize\url{http://mirrors.ctan.org/macros/latex/contrib/listings/listings.pdf}
