Tracking the mouse pointer

In MATLAB, with tooltips, you can know what the value of a line is at a given point:

But if you want to know the value of an arbitrary point in a figure, you will want gtrack:

This is a nice little utility function that can be put on your MATLAB path, and then invoked with a few keystrokes at the command line. I like how the title keeps the X,Y formatted such that as you move the mouse the values do not jump around the title as significant figures in the location change.

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).
