cannam@127 1 FFTW is a free collection of fast C routines for computing the
cannam@127 2 Discrete Fourier Transform in one or more dimensions. It includes
cannam@127 3 complex, real, symmetric, and parallel transforms, and can handle
cannam@127 4 arbitrary array sizes efficiently. FFTW is typically faster than
cannam@127 5 other publically-available FFT implementations, and is even
cannam@127 6 competitive with vendor-tuned libraries. (See our web page
cannam@127 7 http://fftw.org/ for extensive benchmarks.) To achieve this
cannam@127 8 performance, FFTW uses novel code-generation and runtime
cannam@127 9 self-optimization techniques (along with many other tricks).

cannam@127 11 The doc/ directory contains the manual in texinfo, PDF, info, and HTML
cannam@127 12 formats. Frequently asked questions and answers can be found in the
cannam@127 13 doc/FAQ/ directory in ASCII and HTML.

cannam@127 18 INSTALLATION
cannam@127 19 ------------
cannam@127 20
cannam@127 21 INSTALLATION FROM AN OFFICIAL RELEASE:
cannam@127 22
cannam@127 23 Please read chapter 10 "Installation and Customization" of the manual.
cannam@127 24 In short:
cannam@127 25
cannam@127 26 ./configure
cannam@127 27 make
cannam@127 28 make install
cannam@127 29
cannam@127 30 INSTALLATION FROM THE GIT REPOSITORY:
cannam@127 31
cannam@127 32 First, install these programs:
cannam@127 33
cannam@127 34 ocaml, ocamlbuild, autoconf, automake, indent, and libtool,
cannam@127 35
cannam@127 36 Then, execute
cannam@127 37
cannam@127 38 sh bootstrap.sh
cannam@127 39 make
cannam@127 40
cannam@127 41 The bootstrap.sh script runs configure directly, but if you need to
cannam@127 42 re-run configure, you must pass the --enable-maintainer-mode flag:
cannam@127 43
cannam@127 44 ./configure --enable-maintainer-mode [OTHER CONFIGURE FLAGS]
cannam@127 45
cannam@127 46 CONTACTS
cannam@127 47 --------
cannam@127 48
cannam@127 49 FFTW was written by Matteo Frigo and Steven G. Johnson. You can
cannam@127 50 contact them at fftw@fftw.org. The latest version of FFTW,
cannam@127 51 benchmarks, links, and other information can be found at the FFTW home
cannam@127 52 page (http://www.fftw.org). You can also sign up to the fftw-announce
cannam@127 53 Google group to receive (infrequent) updates and information about new
cannam@127 54 releases.
