Constructor & Destructor Documentation

template<unsigned Dim, class T> FFT< RCTransform, Dim, T >::FFT (  const Domain_t &  rdomain, const Domain_t &  cdomain, const bool  transformTheseDims[Dim], const bool &  compressTemps = false )

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

template<unsigned Dim, class T> FFT< RCTransform, Dim, T >::FFT (  const Domain_t &  rdomain, const Domain_t &  cdomain, const bool &  compressTemps = false, int  serialAxes = 1 )

Same as above, but transform all dims:

Member Function Documentation

template<unsigned Dim, class T> void FFT< RCTransform, Dim, T >::transform (  const char *  directionName, ComplexField_t &  f, RealField_t &  g, const bool &  constInput = false )

template<unsigned Dim, class T> void FFT< RCTransform, Dim, T >::transform (  int  direction, ComplexField_t &  f, RealField_t &  g, const bool &  constInput = false )

complex-to-real FFT Same as above, but with input and output field types reversed.

template<unsigned Dim, class T> void FFT< RCTransform, Dim, T >::transform (  const char *  directionName, RealField_t &  f, ComplexField_t &  g, const bool &  constInput = false )

template<unsigned Dim, class T> void FFT< RCTransform, Dim, T >::transform (  int  direction, RealField_t &  f, ComplexField_t &  g, const bool &  constInput = false )

real-to-complex FFT: specify +1 or -1 to indicate forward or inverse transform, or specify the user-defined name string for the direction. Supply a second BareField to store the output. 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.
