In my paper I include Octave code with
\usepackage{listings}
No I want that the text and numbers be written in the same colors as the are represented with in Octave. Everything is fine, except that I don't know how to color the symbols red that have to be red.
For example keywords could easily be colored blue by writing
keywordstyle=\color{blue}
Is there a similar way for doing this with symbols written in red? I did it manually, but this doesn't work as expected.
This is what I wrote in LaTeX:
\documentclass[a4paper]{report}
\usepackage{color}
\usepackage{listings}
\definecolor{mygreen}{rgb}{0,0.6,0}
\definecolor{mygray}{rgb}{0.5,0.5,0.5}
\definecolor{mymauve}{rgb}{0.58,0,0.82}
\definecolor{myorange}{rgb}{0.855,0.576,0.027}
\lstset{
language=Octave,
frame=single,
morecomment = [l][\itshape\color{blue}]{\%},
keywordstyle=\color{blue},
commentstyle=\color{mygreen},
breakatwhitespace=false,
breaklines=true,
numbers=left,
numbersep=5pt,
numberstyle=\tiny\color{mygray},
showstringspaces=false,
showtabs=false,
tabsize=2,
stringstyle=\color{myorange},
title=\lstname,
literate=
{+}{{{\color{red}+}}}1
{-}{{{\color{red}-}}}1
{*}{{{\color{red}*}}}1
{,}{{{\color{red},}}}1
{=}{{{\color{red}=}}}1
{)}{{{\color{red})}}}1
{(}{{{\color{red}(}}}1
{;}{{{\color{red};}}}1
{:}{{{\color{red}:}}}1
{[}{{{\color{red}[}}}1
{]}{{{\color{red}]}}}1
{>}{{{\color{red}>}}}1
}
\begin{document}
\begin{lstlisting}[caption={invar\_table.m}]
function out = invar_table(n,m,N)
if n>m, error('first number must be smaller than the second'), endif
t = cputime;
out = zeros(m-n+1,2);
for i=n:m
out(i+1-n,1) = i;
out(i+1-n,2) = invar(braidmatrix(i),N);
end
printf('Total CPU time: %f seconds\n', cputime-t);
end
\end{lstlisting}
\end{document}
An example of code in my LaTeX document:
And this is how it should look like:
How can I display the colors correctly?
