Constructor & Destructor Documentation

template<class T> FFT< CCTransform, 1U, T >::FFT (  const Domain_t &  cdomain, const bool  transformTheseDims[1U], const bool &  compressTemps = false )

Create a new FFT object with the given domain for the input Field. Specify which dimensions to transform along. Optional argument compressTemps indicates whether or not to compress temporary Fields in between uses.

template<class T> FFT< CCTransform, 1U, T >::FFT (  const Domain_t &  cdomain, const bool &  compressTemps = false )

Create a new FFT object with the given domain for the input Field. Transform along all dimensions. Optional argument compressTemps indicates whether or not to compress temporary Fields in between uses.

Member Function Documentation

template<class T> void FFT< CCTransform, 1U, T >::transform (  const char *  directionName, ComplexField_t &  f )

template<class T> void FFT< CCTransform, 1U, T >::transform (  int  direction, ComplexField_t &  f )

overloaded versions which perform the FFT "in place"

template<class T> void FFT< CCTransform, 1U, T >::transform (  const char *  directionName, ComplexField_t &  f, ComplexField_t &  g, const bool &  constInput = false )

invoke using string for direction name

template<class T> void FFT< CCTransform, 1U, T >::transform (  int  direction, ComplexField_t &  f, ComplexField_t &  g, const bool &  constInput = false )

Do the FFT: specify +1 or -1 to indicate forward or inverse transform, or specify the user-defined name string for the direction. User provides separate input and output fields optional argument constInput indicates whether or not to treat the input Field argument f as const. If not, we can use it as a temporary in order to avoid an additional data transpose.
