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.

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

Factorize the sparse matrix A.

This factorization is used in SparseLinearAlgebraTraitsWithFactor_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

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

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

Returns: true if the solver is successful
