WebThis function computes the one-dimensional n -point discrete Fourier Transform (DFT) of a real-valued array by means of an efficient algorithm called the Fast Fourier Transform (FFT). Number of points along transformation axis in the input to use. If n is smaller than the length of the input, the input is cropped. WebThe Fast Fourier Transform (FFT) is an efficient algorithm to calculate the DFT of a sequence. It is described first in Cooley and Tukey’s classic paper in 1965, but the idea actually can be traced back to Gauss’s unpublished work in 1805.
