Hi guys, My current problem is to check the frequency. I've got pretty complicated function expotentials and stuff, based on sinus. Does matlab provides some function that would check it for me? I could prepare some algorithm to do it, but it seems complicated. fft can't help here, i think.

Have you checked with fft? fft should be able to solve it.

I don't know why you say fft() can't do it. If you don't want that then try pwelch() in the Signal Analysis Toolbox.
