How to Place Two Figures Side by Side in Latex Multicolumn Class

If you are using a multicolumn LaTeX class template, then placing two figures side by side so that they spawn the entire width of the page is done by simply using the {figure*} environment

\begin{figure*}
    \subfigure{...}
    \subfigure{...}
\end{figure*}

Voila!
You may want to move the code for your figure around so that it doesn't show up on the last page. Also, try using [ht] for figure placement

\begin{figure*}[ht]
    \subfigure{...}
    \subfigure{...}
\end{figure*}

This is a typical case with the IEEE Transactions LaTeX template which was the reason for searching the web for this. I learned it from here.
