Readme for fft-

[back to package description]
This package provides bindings to the FFTW library.

You will need to install FFTW version 3, including development files before this
package.  Consult your package manager or visit http://fftw.org to install FFTW.
In addition, the Haskell package carray is required.

  runhaskell Setup.lhs configure
  runhaskell Setup.lhs build
  runhaskell Setup.lhs haddock          (optional)
  runhaskell Setup.lhs install

Then run the tests:

  runhaskell tests/tests.hs

We use the CArray package for multi-dimensional arrays.  It allocates pinned
memory on the GC'd heap, which is 16-byte aligned by default, allowing SIMD
instructions.  If you get a CArray from a foreign source using
unsafeForeignPtrToCArray (an O(1) operation) then you must be sure that the
memory is aligned if you expect SIMD code to be used by FFTW.

A note regarding licensing: FFTW is generally distributed under the GPL,
although a different license can be purchased.  Therefore, the fact that these
bindings are BSD licensed does not mean you can link against a GPL'd copy of
FFTW without complying with the GPL.
