What is FFT library?
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).
What is the most common library for FFT?
FFTW is the most popular FFT library. It has planty of features and it's often used as the reference point, but a number of other libraries has comparable or better performance.
What is FFT C++?
A fast Fourier transform (FFT) is an algorithm to compute the discrete Fourier transform (DFT) and its inverse. Fourier analysis converts time (or space) to frequency and vice versa; an FFT rapidly computes such transformations by factorizing the DFT matrix into a product of sparse (mostly zero) factors.
Where is FFTW installed?
6.1 FFTW MPI Installation
All of the FFTW MPI code is located in the mpi subdirectory of the FFTW package.
