Resize matrix in LaTeX beamer

Question

Hi I was wondering how to resize matrices in a beamer environment. Currently I am writing the following code:

\begin{align*}
\left( \begin{array}{ccccccc}
 0 & 1 &    &   &        &    &   \\
-1 & 0 &    &   &        &    &   \\
   &   &  0 & 1 &        &    &   \\
   &   & -1 & 0 &        &    &   \\
   &   &    &   & \ddots &    &   \\
   &   &    &   &        & 0  & 1 \\
   &   &    &   &        & -1 & 0
\end{array} \right)
\end{align*}

and the matrix takes up almost a whole page. I would like it to be about half a page in height.

See this answer for how to change font dimensions in LaTeX's math mode.

Edit

Specifying font sizes in beamer is no different from specifying them in other LaTeX documents. To e.g. change the size of your array you would switch the size by adding the command inside your align environment.

Valid commands are \tiny, \scriptsize, \footnotesize, \small, \normalsize, \large, \Large, \huge, and \Huge (there could be more).
