Update to timeit

On Leap Day, 2008, I posted about how to time code in MATLAB, and I gave a link to a timing utility function called timeit that I submitted to the MATLAB Central File Exchange.

If you use timeit, you might want to download the updated version I posted last week. It corrects a problem that occurred when timing anonymous function handles.

Wrap code fragments inside <pre> tags, like this:

<pre class="code">
a = magic(3);
sum(a)
</pre>

If you have a "<" character in your code, either follow it with a space or replace it with "&lt;" (including the semicolon).
