template<typename T>
void sgpp::datadriven::OperationMultiEvalStreamingModOCLFastMultiPlatform< T >::mult ( base::DataVector alpha,
base::DataVector result 
)
inlineoverridevirtual

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.

template<typename T>
void sgpp::datadriven::OperationMultiEvalStreamingModOCLFastMultiPlatform< T >::prepare ( )
inlineoverridevirtual

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.
