linear_solver()

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()
