FFTW3
FFTW is a subroutine library written in C for computing the Discrete Fourier Transform in one or more dimensions, of both real and complex data, of arbitrary input size. FFTW can be called from Fortran and C++ as well as from C codes.
FFTW is free software as defined by the Free Software Foundation and is distributed under the terms of the GNU General Public License. It is callable from Fortran, and works on any platform with a C compiler.
FFTW was developed at MIT by Matteo Frigo and Steven G. Johnson.
Please note: FFTW3 is not compatible with version 2.
