Member Function Documentation

getDuration()

double sgpp::datadriven::OperationMultiEvalHPX::getDuration ( )

virtual

Implements sgpp::base::OperationMultipleEval.

References duration.

mult()

void sgpp::datadriven::OperationMultiEvalHPX::mult ( sgpp::base::DataVector &  alpha, sgpp::base::DataVector &  result  )

virtual

Multiplication of \(B^T\) with vector \(\alpha\).

Parameters

alpha	vector, to which \(B\) is applied. Typically the coefficient vector
result	the result vector of the matrix vector multiplication

Implements sgpp::base::OperationMultipleEval.

multTranspose()

void sgpp::datadriven::OperationMultiEvalHPX::multTranspose ( sgpp::base::DataVector &  source, sgpp::base::DataVector &  result  )

virtual

Multiplication of \(B\) with vector \(\alpha\).

Parameters

source	vector, to which \(B^T\) is applied. Typically the coefficient vector
result	the result vector of the matrix vector multiplication

Implements sgpp::base::OperationMultipleEval.

References duration, myTimer, sgpp::base::SGppStopwatch::start(), and sgpp::base::SGppStopwatch::stop().

prepare()

void sgpp::datadriven::OperationMultiEvalHPX::prepare ( )

virtual

Used for kernel-specific setup like special data structures that are defined from the current state of the grid.

This function is by default called with each "mult()", "multTranspose()" or evaluation operation and can be ignored from an external perspective. This is not overridden by every kernel.

Reimplemented from sgpp::base::OperationMultipleEval.
