Signalanalyse fft
WebThe FFT is calculated along the first non-singleton dimension of the array. Thus if x is a matrix, fft ( x ) computes the FFT for each column of x . If called with two arguments, n is expected to be an integer specifying the number of elements of x to use, or an empty matrix to specify that its value should be ignored.
