I want to use listings package (\usepackage{listings}) to show a matlab code in a paper (using elsarticle class) but the title is not aligned in center below the code. This happened after I added xleftmargin=3.5cm and xrightmargin=3.5cm to add margin from left and right. If I remove these two options, title appears at the center of page! How can I have both margin and center title with listings?
I used \centering and \begin{center}...\end{center} but they didn't work.
UPDATE: I found out that \usepackage{subcaption} is the problem. without it title will be centered. But I need subcaption!
my code:
\documentclass[3p,times]{elsarticle}
\usepackage{ecrc}
\volume{00}
\firstpage{1}
\journalname{Best Journal Ever}
\runauth{S. Gerami}

UPDATE2: I tested method proposed in following link and not worked: Center caption in listing
but then I saw this answer and edited to this:
\begin{figure}[thp]
\begin{center}
\begin{lstlisting}[numbers=left]
My Code
Another line
\end{lstlisting}
\end{center}
\caption{my caption or title}
\end{figure}
result:
It's good but the gap between box and caption is too much. I need to reduce it for good result.
UPDATE3: This link has the best answer to removing gap for just one figure.

But I need subcaption in my paper. I'll update the code with a simple example. – sajjadG Sep 23 '13 at 20:06\captioncommand inside thecenterenvironment and add\vspace*{-\baselineskip}just before\caption. – Andrew Swann Sep 24 '13 at 11:15captionmanual? – Martin Schröder Sep 25 '13 at 19:19listingspackage overwritecaptionsetting and it can be overwritten back by\captionsetup[lstlisting]{justification=centering}. Interesting. where were you to mention this when I was like this :-S Thanks. I test it later. – sajjadG Sep 25 '13 at 19:29matlab-prettifierpackage; see this answer. – jub0bs Apr 28 '14 at 15:47
