How can I Transform the time series data into frequency domain using Fast Fourier Transformed (FFT)

6 views (last 30 days)
I have the Magnetotellric data in excel and I wrote a MATLAB code to import the data into MATLAB. The problem is that the data were recorded in time series and the challenge now is to transform these data into frequency domain using the Fast Fourier Transformed. Please help

doc fft
gives example of a psd. Otherwise, this is not really a Matlab question but one of application of FFT.
