Installation

First, make sure FFTW3 is installed on your system. This package only requires the binary shared libraries (.so, .dylib, .dll). Please see your package management system to install FFTW3. You can also download and compile fftw3 from FFTW3 web page

luarocks install https://raw.github.com/soumith/fftw3-ffi/master/rocks/fftw3-scm-1.rockspec

Usage

local fftw = require 'fftw3'
...

Float version

local fftw = require 'fftw3'
fftw = fftw.float
...

All FFTW C functions are available in the fftw namespace returned by require. The only difference is the naming, which is not prefixed by fftw_ anymore.
