double sgpp::datadriven::OperationMultiEvalMPI::getDuration ( )
virtual
void sgpp::datadriven::OperationMultiEvalMPI::mult ( sgpp::base::DataVector alpha,

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

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

Implements sgpp::base::OperationMultipleEval.

void sgpp::datadriven::OperationMultiEvalMPI::multTranspose ( sgpp::base::DataVector source,
sgpp::base::DataVector result 
)
virtual

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

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

Implements sgpp::base::OperationMultipleEval.

References duration, and python.leja::start.

void sgpp::datadriven::OperationMultiEvalMPI::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.
