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).

Note:
  This package contains the fftw libraries for single, double and long-double precision 
  for both 32 and 64-bits.

Requirements:
  NA
