com.imsl.test.example.math.GenMinResEx1

All Implemented Interfaces:

GenMinRes.Function

public class GenMinResEx1
extends Object
implements GenMinRes.Function

Solves a small linear system with the Generalized Minimum Residual (GMRES) method.

A solution to a small linear system is found. The coefficient matrix is stored as a full matrix and no preconditioning is used. Typically, preconditioning is required to achieve convergence in a reasonable number of iterations.
