http://fftw.org/ 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It is described first in Cooley and Tukey’s classic paper in 1965, but the idea actually can be traced back to Gauss’s unpublished work in 1805. thecal indentation meaningWebFast Fourier Transforms Transform vectors and matrices of temporal and spatial domain complex values to the frequency domain, and vice versa.
