library for computing Fast Fourier Transforms
This library computes Fast Fourier Transforms (FFT) in one
or more dimensions. It is extremely fast. This package
contains the documentation and the shared version of the fftw
libraries. To get the static library and the header files you
need to install fftw1-dev.
This is FFTW, v. 2.0. FFTW is a collection of fast C routines to
compute the Discrete Fourier Transform in one or more dimensions.
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
fftw for DEBIAN
The libraries of fftw in Debian are heavily optimized and not
threaded. There is code in the source for creating a threaded
version. If anyone is interested in a threaded version of fftw,
send me mail and I will create a separate package containing

This file contains a random collection of the various hacks we did (or
did not dare to do) in order to get performance. It is not intended
to be complete nor up to date, but it may be instructive for people to
read (see also my (Matteo Frigo's) slides on the web page).
1) Negative constants:
a = 0.5 * b; a = 0.5 * b;
c = 0.5 * d; c = -0.5 * d;
This directory contains a test program, fftw_test, for the one- and
multi-dimensional transforms. T
