Constructor & Destructor Documentation

template<class T> FFT< SineTransform, 1U, T >::FFT (  const Domain_t &  rdomain, const bool  sineTransformDims[1U], const bool &  compressTemps = false )

Constructors for doing only sine transforms Create a new FFT object with the given domain for input/output Field specify which dimensions to transform along. Optional argument compress indicates whether or not to compress temporary Fields in between uses.

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

Same as above, but transform all dims:

template<class T> FFT< SineTransform, 1U, T >::~FFT (  void   )

Member Function Documentation

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

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

In-place version of real-to-real transform

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

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

sine transform: 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.
