Detailed Description

template<class T>
class Arroyo::rfft_manager< T >

A template class to facilitate real to complex forward and backward fft's using fftw. This class aims to make arbitrary-dimensional fast fourier transforms relatively straightforward, and supports all the FFTW options

Member Function Documentation

template<class T> void Arroyo::rfft_manager< T >::complex_to_real_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 real transform as above, with more options 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

template<class T> void Arroyo::rfft_manager< T >::complex_to_real_fft (  const vector< long > &  in_array_dimens, bool  estimate, bool  in_place, T *  in, T *  out = NULL )

Perform a complex to real 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.

template<class T> rfft_manager< T > & Arroyo::rfft_manager< T >::operator= (  const rfft_manager< T > &  rfft_mgr  )

Operator =

template<class T> void Arroyo::rfft_manager< T >::real_to_complex_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 real to complex transform as above, with more options 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

template<class T> void Arroyo::rfft_manager< T >::real_to_complex_fft (  const vector< long > &  in_array_dimens, bool  estimate, bool  in_place, T *  in, T *  out = NULL )

Perform a real to complex transform input data should be sorted real, real, real... Some warnings are in order here: The transformed array requires slightly more storage than the original if the final axis is even, because of nyquist. See the FFTW home page for a discussion of this issue and for the output array format.
