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

在 MATLAB Online 中打开

doc fft

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