Lighter matlab descrete convolution software

[liquidFuzz]

A while back I tended a course in transform methods. During the course we were handed a MAtlab program that could be used to simulate convotution called Discrete Convolution Demo. It's kind of big or you might say bloated and I'd like some lightweight version or something. If someone know some nice MATLAB code to use that's lighter, I really like some suggestions.

Cheers!

I found this: conv() and it's just dandy.
