So I have time-varying force data. The force acts as a concentrated load. The force does not vary periodically/harmonically, it just has a general variation with time. My main question is: How do I determine the corresponding frequency of this force data?

Also, if I'm using MATLAB and I have a data vector of this force's time variation, how do I use MATLAB to determine the corresponding frequency data? Do I use the fft() function?

Any help/insight would be appreciated! Let me know if you need any more details and I will happily provide them.

Thanks
