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.

Answer 1

There is the \resizebox command in the graphicx package:

\resizebox{.5\textwidth}{!}{  (your array here)  }

I've never tried it, but it looks as it is made exactly for this kind or problem.

Of course, you can choose different widths (first argument) or different height (second argument) parameters.
