Introduction FFTW is a C subroutine library for computing the discrete Fourier transform (DFT) in one or more dimensions, of arbitrary input size, and of both real and complex data (as well as of even/odd data, i.e. the discrete cosine/sine transforms or DCT/DST). We believe that FFTW, which is free software, should become the FFT library of choice for most applications.

Dec 06, 2019 · The fast Fourier transform (FFT) is a discrete Fourier transform algorithm which reduces the number of computations needed for N points from 2N^2 to 2NlgN, where lg is the base-2 logarithm. FFTs were first discussed by Cooley and Tukey (1965), although Gauss had actually described the critical factorization step as early as 1805 (Bergland 1969, Strang 1993).

The FFT is a complicated algorithm, and its details are usually left to those that specialize in such things. This section describes the general operation of the FFT, but skirts a key issue: the use of complex numbers.If you have a background in complex mathematics, you can read between the lines to understand the true nature of the algorithm.



La transformation de Fourier rapide (sigle anglais : FFT ou fast Fourier transform) est un algorithme de calcul de la transformation de Fourier discrète (TFD). Sa complexité varie en O(n log n) avec le nombre n de points, alors que la complexité de l’algorithme « naïf » s’exprime en O(n 2).
