Project with MATLAB GUIDE

Hello everybody,

I have a little issue here, I need ideas for my fundamentals of electrical systems but I don't have idea of what to do, I'm not an electrical engineering student I'm a computer science student so knowledge of this topics are poor. In the class the only thing we see that we use MATLAB, we are studying signals like sign function, Dirac delta function, signals basic operations. I would appriciate if some of you give me a little of ideas and another point I need to GUIDE.

Thank you.
