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

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

| 15 For a quick introduction to calling FFTW, see the "Tutorial" section | |
| 16 of the manual. | |

| 18 INSTALLATION | |
| 19 ------------ | |
| 20 | |
| 21 INSTALLATION FROM AN OFFICIAL RELEASE: | |
| 22 | |
| 23 Please read chapter 10 "Installation and Customization" of the manual. | |
| 24 In short: | |
| 25 | |
| 26 ./configure | |
| 27 make | |
| 28 make install | |
| 29 | |
| 30 INSTALLATION FROM THE GIT REPOSITORY: | |
| 31 | |
| 32 First, install these programs: | |
| 33 | |
| 34 ocaml, ocamlbuild, autoconf, automake, indent, and libtool, | |
| 35 | |
| 36 Then, execute | |
| 37 | |
| 38 sh bootstrap.sh | |
| 39 make | |
| 40 | |
| 41 The bootstrap.sh script runs configure directly, but if you need to | |
| 42 re-run configure, you must pass the --enable-maintainer-mode flag: | |
| 43 | |
| 44 ./configure --enable-maintainer-mode [OTHER CONFIGURE FLAGS] | |
| 45 | |
| 46 Alternatively, you can run | |
| 47 | |
| 48 sh mkdist.sh | |
| 49 | |
| 50 which will run the entire bootstrapping process and generate | |
| 51 .tar.gz files similar to those for official releases. | |
| 52 | |
| 53 CONTACTS | |
| 54 -------- | |
| 55 | |
| 56 FFTW was written by Matteo Frigo and Steven G. Johnson. You can | |
| 57 contact them at fftw@fftw.org. The latest version of FFTW, | |
| 58 benchmarks, links, and other information can be found at the FFTW home | |
| 59 page (http://www.fftw.org). You can also sign up to the fftw-announce | |
| 60 Google group to receive (infrequent) updates and information about new | |
| 61 releases. |
