Member Function Documentation

FFT_initialize_Target()

void FFTAcceleration_blocks::FFT_initialize_Target ( FFTAccelerableExpansion &  Expansion )

virtual

Initialize a Target expansion's FFTDatacontainer (schould be to a full 0 FFTDatacontainer)

Parameters

FFTAccelerableExpansion

& Expansion

Implements FFTAccelerationAPI.

FFT_M2L()

void FFTAcceleration_blocks::FFT_M2L ( FFTAccelerableExpansion &  Source, FFTAccelerableExpansion &  Target, FFTDataContainer *  TransferFunction  )

virtual

M2L operator, performs the M2L in fourier space, usually an entrywise product (or more complexe scheme if needed, see blocks implementations)

All parameters needs to be initialized using the previous methods The TransferFunction should come from a TransferFunctionManager

Parameters

FFTDataContainer*	TransferFunction

Implements FFTAccelerationAPI.

FFT_M2L_2way()

void FFTAcceleration_blocks::FFT_M2L_2way ( FFTAccelerableExpansion &  Source1, FFTAccelerableExpansion &  Source2, FFTAccelerableExpansion &  Target1, FFTAccelerableExpansion &  Target2, FFTDataContainer *  TransferFunction  )

virtual
