Double BackError { get; set; }
Holds the backward or iterative stopping criteria.
Returns: Double
Remarks:
After running direct solver (Dew.Math.TSparseMtx.Solve method) with active iterative refinement (Dew.Math.TSparseMtx.RefinmentIters > 0) the property holds the backward error. In case of iterative solvers (Dew.Math.TSparseMtx.SolveIterative method), the property holds the error according to the stoping criteria (see Dew.Math.TSparseMtx.ConvergenceCheck property).
