FFTW

FFTW

FFTW (signifiant Fastest Fourier Transform in the West, soit Transformée de Fourier la plus rapide de l'Ouest) est une bibliothèque informatique calculant des transformées de Fourier discrète, développée par Matteo Frigo et Steven G. Johnson au Massachusetts Institute of Technology.

FFTW est utilisé par MATLAB pour les calculs de transformées de Fourier.

En 1999, FFTW a gagné le Prix J. H. Wilkinson pour le logiciel numérique.
