Interface to FFTW, version 3

Perquisites

The FFTW, version 3, with its development files (fftw3.h) must be
installed on your platform. For example, on Debian or Ubuntu, you
need to install the package libfftw3-dev.

Compilation

./bootstrap (optional, requires autoconf)
./configure
make

If your fftw3 header files or libraries are not where you C compiler
expects to find them, you need to tell configure by using the
following syntax:

CPPFLAGS="-I/opt/local/include" LDFLAGS="-L/opt/local/lib" ./configure

Of course, replace /opt/local/include (resp. /opt/local/lib) by the
actual paths of your header files (resp. library).

Usage

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.

Examples

Some examples need additional libraries:
- Lacaml
- Archimedes

If these are not detected by the configure script, the corresponding
examples will not be compiled or will have less features.

Bugs

issues page.
