Matrix.ForwError Property

Matrix Class

property ForwError: Double;

The component-wise forward error.

Returns: Double

Remarks:

Set by the Matrix.LUSolve method, if the Matrix.RefineSolution property was True. The ForwError property returns the component-wise forward error in the computed solution:

∥x−xe∥∞∥x∥∞where xe is an exact solution.\frac{\| x-x_e\|_\infty }{\|x\|_\infty} \quad \text{where } x_e \text{ is an exact solution.}
