I have a 2 column vector with times and speeds of a subset of data, like so:
5 40
10 37
15 34
20 39
And so on. I want to get the fourier transform of speeds to get a frequency. How would I go about doing this with a fast fourier transform (fft)?
If my vector name is sampleData, I have tried
fft(sampleData);
but that gives me a vector of real and imaginary numbers. To be able to get sensible data to plot, how would I go about doing this?
