Member Function Documentation

template<class C>

virtual void MathTL::MatrixBlock< C >::apply	(	const Vector< C > &	x,
		Vector< C > &	Mx
	)		const [pure virtual]

matrix-vector multiplication Mx = (*this) * x; we assume that the vector Mx has the correct size and is not identical to x

Implemented in MathTL::Matrix< C >, MathTL::Matrix< double >, MathTL::SparseMatrix< C >, MathTL::BlockMatrix< C >, and MathTL::KroneckerMatrix< C, MATRIX1, MATRIX2 >.

template<class C>

virtual void MathTL::MatrixBlock< C >::apply_transposed	(	const Vector< C > &	x,
		Vector< C > &	Mtx
	)		const [pure virtual]

transposed matrix-vector multiplication Mtx = (*this)^T * x; we assume that the vector Mtx has the correct size and is not identical to x

Implemented in MathTL::Matrix< C >, MathTL::Matrix< double >, MathTL::SparseMatrix< C >, MathTL::BlockMatrix< C >, and MathTL::KroneckerMatrix< C, MATRIX1, MATRIX2 >.
