FFTW_Ada - An Ada 95 binding to the FFTW library
http://fftwada.sourceforge.net/
FFTW_Ada is an Ada 95 binding to the FFTW library written at MIT by Matteo Frigo and Steven G. Johnson. FFTW is a library for computing the Fast Fourier transform, which is both fast, and copes with arbitrary sizes of array, in multiple dimensions. FFTW is written in C and the purpose of FFTW_Ada is to allow calls to FFTW from an Ada 95 or Ada 2005 program.
