Detailed Description

template<typename ValueType>
class Bempp::TransposedDiscreteBoundaryOperator< ValueType >

Transposed and/or conjugated discrete boundary operator.

This class represents a transposed, conjugated or conjugate-transposed discrete boundary operator scalar.

Constructor & Destructor Documentation

template<typename ValueType >

Bempp::TransposedDiscreteBoundaryOperator< ValueType >::TransposedDiscreteBoundaryOperator	(	TranspositionMode	trans,
		const shared_ptr< const Base > &	op
	)

Constructor.

Construct the discrete boundary operator representing the transpose, conjugate or conjugate transpose of the operator op.

References Bempp::CONJUGATE, Bempp::CONJUGATE_TRANSPOSE, Bempp::NO_TRANSPOSE, and Bempp::TRANSPOSE.

Member Function Documentation

template<typename ValueType >

void Bempp::TransposedDiscreteBoundaryOperator< ValueType >::addBlock	(	const std::vector< int > &	rows,
		const std::vector< int > &	cols,
		const ValueType	alpha,
		arma::Mat< ValueType > &	block
	)		const

virtual

Add a subblock of this operator to a matrix.

Perform the operation block += alpha * L[rows, cols], where block is a matrix, alpha a scalar and L[rows, cols] a subblock of this discrete linear operator.

Parameters

[in]	rows	Vector of row indices.
[in]	cols	Vector of column indices.
[in]	alpha	Multiplier.
[in,out]	block	On entry, matrix of size (`rows.size()`, `cols.size()`). On exit, each element (i, j) of this matrix will be augmented by the element (`rows[i]`, `cols[j]`) of this operator, multiplied by `alpha`.

Row and column indices may be unsorted.

This method need not be supported by all subclasses. It is mainly intended for internal use during weak-form assembly.

Implements Bempp::DiscreteBoundaryOperator< ValueType >.

template<typename ValueType >

arma::Mat< ValueType > Bempp::TransposedDiscreteBoundaryOperator< ValueType >::asMatrix ( ) const

virtual

Matrix representation of the operator.

The default implementation is slow and should be overridden where possible.

Reimplemented from Bempp::DiscreteBoundaryOperator< ValueType >.
