Definition

Concept describing the set of requirements for a direct sparse linear system solver with factorization. A model of this concept stores the left-hand matrix (denoted \( A \)) and provides an additional factorization method to solve the system for different right-hand vectors.

Constructor & Destructor Documentation

◆ SparseLinearAlgebraWithFactorTraits_d()

SparseLinearAlgebraWithFactorTraits_d::SparseLinearAlgebraWithFactorTraits_d ( )

Default constructor.

Member Function Documentation

◆ factor()

bool SparseLinearAlgebraWithFactorTraits_d::factor	(	const Matrix &	A,
		NT &	D
	)

Factorize the sparse matrix A.

This factorization is used in SparseLinearAlgebraWithFactorTraits_d::linear_solver() to solve the system for different right-hand side vectors. See SparseLinearAlgebraTraits_d::linear_solver() for the description of D.

Returns: true if the factorization is successful and false otherwise.

◆ linear_solver() [1/2]

bool SparseLinearAlgebraWithFactorTraits_d::linear_solver	(	const Matrix &	B,
		Vector &	X
	)

Solve the sparse linear system \( A \times X = B\), with \( A \) being the matrix provided in SparseLinearAlgebraWithFactorTraits_d::factor().

Returns: true if the solver is successful and false otherwise.

◆ linear_solver() [2/2]

bool SparseLinearAlgebraWithFactorTraits_d::linear_solver	(	const Vector &	B,
		Vector &	X
	)
