How do you implement Fourier transform in MATLAB?

Use a time vector sampled in increments of 1/50 seconds over a period of 10 seconds. Compute the Fourier transform of the signal, and create the vector f that corresponds to the signal's sampling in frequency space. y = fft(x); fs = 1/Ts; f = (0:length(y)-1)*fs/length(y);
