Introduction to FFTW
FFTW is a C subroutine library for computing the discrete Fourier transform (DFT) in one or more dimensions. The name, "FFTW," stands for "Fastest Fourier Transform in the West." FFTW was developed at MIT, which is in the east. DJBFFT is an alternative that claims to be faster.

Dependencies
Optional
- Objective Caml
- OpenMP is required if passing the --with-openmp: switch to the configure script.
Configuration Information
Some options that you may wish to pass to the configure script.
| --enable-single: compile FFTW in single precision. | ||||||||
| --enable-long-double: compile FFTW in long-double precision. | ||||||||
| --enable-k7: enable AMD k7 optimizations, including 3dNow! | ||||||||
| --enable-sse: enable SSE optimizations. | ||||||||
| --enable-sse2: enable SSE2 optimizations. | ||||||||
| --disable-fortran: don't include FORTRAN callable wrappers. | ||||||||
--with-openmp: use OpenMP directives instead of a threads library.
