The terms in the matrix below are actually very wide and it should be inserted in a two column page format, so I would like to put it with the whole width of the page at the end of the page. I was wandering if there is a way to make it as included in the attached image.
\documentclass[conference,a4paper]{IEEEtran}
\begin{document}
\begin{align*}
\mathbf{D} & =\begin{pmatrix}
& a & b & \cdots & c\\
& a & b & \cdots & c\\
&\vdots & \vdots & \vdots & \vdots\\
& a & b & \cdots & c\\
\end{pmatrix}
\end{align*}
\end{document}
