matrix with small font

[Ken]

Probably trivial, but how does one apply a different font size to an
entire matrix, or better yet, all items within an align environment?
I know I can use \scriptstyle for each element of a matrix, but that
gets real tedius. Appreciate suggestions. Thanks.

You can enclose your enviroment between:

\small % or \footnotesize or whatever you want
\begin(...)
...
\end(...)
\normalsize

Ah, I was using the wrong terminology - I'd tried \scriptstyle and
\displaystyle and they didn't work, but \small and \normalsize do.
Thanks!

Ken,

Like many programming languages, LaTeX also allows you to use
delimiters to group certain code fragments and define some form of
scope. In your case, the following would also work:

...
{ % or \begingroup
\small
\begin{...}
...
\end{...}
} % or \endgroup
...

The above snippet allows a temporary change to the font size (\small
in this case), without the requirement to switch back to \normalsize
once the scope of the change is finished.
