Member Function Documentation

bool SparseLinearAlgebraTraits_d::linear_solver	(	const Matrix &	A,
		const Vector &	B,
		Vector &	X,
		NT &	D
	)

Solve the sparse linear system A $\times$ X = B.

Return true on success. The solution is then (1/D) $\times$ X.

Precondition: A.row_dimension() == B.dimension(); A.column_dimension() == X.dimension()
