Summary
The component-wise backward error.Class
TMtx
Declaration
Property BackError: TSample read FBackError;
Description
Set by the LUSolve method, if the RefineSolution property was True. The BackError property returns the component-wise backward error b. The backward error is the smallest relative perturbation in elements of A (where A is the calling matrix) and b such that x is the exact solution of the perturbed system:
The BackError property is calculated only if the RefineSolution property is set to true.
