Constructor & Destructor Documentation

AdditionalData()

template<typename MatrixType = SparseMatrix<double>>

PreconditionPSOR< MatrixType >::AdditionalData::AdditionalData	(	const std::vector< size_type > &	permutation,
		const std::vector< size_type > &	inverse_permutation,
		const typename PreconditionRelaxation< MatrixType >::AdditionalData &	parameters = typename PreconditionRelaxation< MatrixType >::AdditionalData()
	)

Constructor. For the parameters' description, see below.

The permutation vectors are stored as a reference. Therefore, it has to be assured that the lifetime of the vector exceeds the lifetime of the preconditioner.

The relaxation parameter should be larger than zero and smaller than 2 for numerical reasons. It defaults to 1.
