Hello,
I write the matrix as
\begin{matrix}
0 & 0 & 0 & \cdots & 0 & 0 & 1 \\
0 & b & 0 & \cdots & 0 & 0 & 2 \\
0 & 0 & c & \cdots & 0 & 0 & 3 \\
\vdots & \vdots & \vdots & & \vdots & \vdots & \vdots \\
0 & 0 & 0 & \cdots & x & 0 & n-1 \\
0 & 0 & 0 & \cdots & 0 & y & n
\end{matrix}
You can try the online latex equation editor:
http://www.codecogs.com/latex/eqneditor.php
It provides a lot features to edit equations, including several kinds of
matrix.
