## Cryptography in MATLAB: Code review

This video assumes you have watched this video that outlines a simple encryption algorithm. The video shows a quick code review of my algorithm. Warning: this video is part of a longer series, I have purposefully left in one syntax error and one inefficiency so that we can use the debugger and profiler later in the series to find and fix these problems.

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).
