This is FFTW, a collection of fast C routines to compute the Discrete
Fourier Transform in one or more dimensions.

`OFFICIAL' CODE:

The doc/ directory contains the manual in texinfo, postscript, info,
and HTML formats.  Frequently asked questions and answers can be found
in the FAQ/ directory in a variety of formats (including HTML).

The fftw/ directory contains the source code for the complex transforms,
and the rfftw/ directory contains the source code for the real transforms.

Large portions of the source are automatically generated by a program
in the gensrc/ directory (written in Objective Caml).  You do not need
this program to use FFTW, since FFTW comes with a default set of
pregenerated codelets.  You are, however, welcome to look at and play
with the generator (see the FFTW manual for more information).

The threads/ directory contains an parallel version of FFTW (for
shared-memory machines) that uses threads.  See the "Multi-threaded
FFTW" section of the manual for more information.
