Puzzler: Data exploration

This is a puzzler without explanation. Brett got it in about five minutes, some of the other folks wandering near my office got it in just under 20.

The data to explore.

Remember to use the <pre><code> and </code></pre> tags around your code in the comments.

First solution in my mailbox as instructed was exactly an hour later. Have fun playing with it still. Congrats to Arthur for the win!

Doug first used MATLAB in 1994, could not figure it out until he got some help in 1995. He is now dedicated to making sure that no one else wastes a year of their life not knowing MATLAB like he did.

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).
