Detailed Description

template<class T>
class Arroyo::fft_manager< T >

A template class to facilitate complex to complex forward and backward fft's. Currently this class supports fftw, but support for additional fft libraries may be added at a later time. For example, conditional compilation of native fft libraries should be possible.

This class aims to make arbitrary-dimensional fast fourier transforms relatively straightforward, and supports all the FFTW options

template<class T> void Arroyo::fft_manager< T >::backward_fft (  const vector< long > &  in_array_dimens, bool  estimate, bool  in_place, int  howmany, T *  in, int  istride, int  idist, T *  out = NULL, int  ostride = 1, int  odist = 1 )

Perform a complex to complex forward transform input data should be sorted real, imag, real, imag... The "out" argument is optional - if you include it an out of place transform will be performed and the results will be stored there. See the FFTW documentation for a description of istride, idist, ostride and odist
