- FFTW is a free collection of fast C routines for computing the
- Discrete Fourier Transform in one or more dimensions. It includes
- complex, real, symmetric, and parallel transforms, and can handle
- arbitrary array sizes efficiently. FFTW is typically faster than
- other publically-available FFT implementations, and is even
- competitive with vendor-tuned libraries. (See our web page for
- extensive benchmarks.) To achieve this performance, FFTW uses novel
- code-generation and runtime self-optimization techniques (along with
- many other tricks).
-
- The doc/ directory contains the manual in texinfo, PDF, info, and HTML
- formats. Frequently asked questions and answers can be found in the
- doc/FAQ/ directory in ASCII and HTML.
-
- For a quick introduction to calling FFTW, see the "Tutorial" section
- of the manual.
-
- Installation instructions are provided in the manual (don't worry, it
- is straightforward).

- CONTACTS
- --------
-
- FFTW was written by Matteo Frigo and Steven G. Johnson. You can
- contact them at fftw@fftw.org. The latest version of FFTW,
- benchmarks, links, and other information can be found at the FFTW home
- page (http://www.fftw.org). You can also sign up to the fftw-announce
- mailing list to receive (infrequent) updates and information about new
- releases; to do so, go to:
