Problems with mdframed

Question

I am trying to put a box around matlab code but the bottom of the box sits extremely close to the next line. I try a line break but it does not work. Any ideas?

\documentclass[a4paper,12pt]{article}
\usepackage{mdframed}
\begin{document}
...get,\\

\begin{mdframed}
\begin{verbatim}
S = 55; % Value of the underlying
...
V =
    2.2147   %This is the value of our put option
\end{verbatim}
\end{mdframed}
\end{document}
bla bla bla

Answer 1

You can add vertical space above and below an mdframed environment by assigning nonzero (length) values to the skipabove and skipbelow optional keys, respectively. For instance:

\documentclass{book}

\usepackage{mdframed}

\begin{document}

_{This is to show an alternative for matlab code with highlighting.}

It is better to use mcode to typeset the matlab codes. mcode internally uses listings package and offers features like different colored text etc.

An example:

\documentclass{article}

% load package with ``framed'' and ``numbered'' option.
\usepackage[framed,numbered,autolinebreaks,useliterate]{mcode}
\lstset{
    rulecolor=\color{black}
}

% something NOT relevant to the usage of the package.
\setlength{\parindent}{0pt}
\setlength{\parskip}{18pt}

\begin{document}
 The following demo block shows some matlab code:
\begin{lstlisting}
for i = 1:3
    if i >= 5                    % literate programming replacement some thing to fill in the space
        disp('cool');           % comment with some §\mcommentfont\LaTeX\ in it: $\mcommentfont\pi x^2$§
    end
    really really long really really long really really long really really long really really long line % blaaaaaaaa
end
\end{lstlisting}
\end{document}

You can add captions by using

\begin{lstlisting}[caption=My code here]
