Matrix scaling in LaTeX beams

Question

Hi, I was wondering how to resize matrices in a ray environment. I am currently 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 tall.

Answer 1

See this answer on how to change font size in LaTeX math mode.

Edit

Setting the font sizes in the control panel is no different from setting them in other LaTeX documents. E.g. resize your array, which you would resize by adding a command to the environment align.

Valid commands: t21, t2, t2, / p>

Answer 2

graphicx \resizebox:

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