+ 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
