Library binding the seminal library FFTW.
Published: 31 Dec 2019
Interface to FFTW, version 3
The FFTW, version 3, with its development files (
fftw3.h) must be installed on your system. For example, on Debian or Ubuntu, you need to install the package
libfftw3-dev (see the package conf-fftw3 for other distributions — click the “Edit” link).
The easier way to install this library is by using opam:
opam install fftw3
If you cloned this repository, you can use Dune to compile it:
dune build @install
If your fftw3 header files or libraries are not where you C compiler expects to find them and
pkg-config does not return the right location either, you need to tell the discover script where to find them by setting the environment variable
Of course, replace
/opt/local/lib) by the actual paths of your header files (resp. library).
Fftw3 contains two submodules differing only by precision
Fftw3.D for double precision and
Fftw3.S for single precision. Note that the functions of the single precision module will raise
Failure if the corresponding FFTW3 library was not discovered by the configure script. See the mli file for more details or consult the documentation online.
Some examples need additional libraries:
If these are not detected by the configure script, the corresponding examples will not be compiled or will have less features.

If you want to participate to the development of Fftw3, make a fork of the project and submit a pull request.
FFtw3 is released under the LGPL with the special exception of the standard library. See the file LICENSE for more details.
