Detailed Description

C++ interface to the FFTWw library.

Synopsis

This is a wrapper of FFTW3. It is only active if FFTW3 was found during the build. If not found, all functions won't do anything at all.

The interface is such that the presence of FFTW3 is only visible in the implementation. The header file does not need to know. In this way external code using this class does not need to set HAVE_FFTW.
