I have this sine function:
10*sin(1000*t)
How do I extract the Amp=10 and the frequency=1000 as variables from that function?
Thanks.

@MAC, your quesiton does not appear to be about Matlab as much as math. Unless you are talking about automated parsing of code, which I doubt. It is a math question. The site is not a homework-answering service. By the way, the frequency of that function is not 1000, if your units are cycles per unit time.

Use the fft function. Calculated, interpreted, and plotted correctly, it will give all that information.
