Fourier transform of input data with varying sampling frequency

Hello, Could someone guide me with the code to plot the FFT of the attached data, since the sampling frequency of input data I have here is varying.

Thanks a lot.

@Paul okay thanks i will take a look at this function

FFT only works with constant sample time by definition. Try using the interp1 function to resample the data set into a fixed sample time.

ok Benjamin thanks I will try to run this
