Y = fft (X) computes the discrete Fourier transform (DFT) of X using a fast Fourier transform (FFT) algorithm. If X is a vector, then fft (X) returns the Fourier transform of the vector. If X is a matrix, then fft (X) treats the columns of X as vectors and returns the Fourier transform of each column. bmw e39 528i radiator fan shroud
