Detailed Description

CG for indefinite Linear Solver.

Author:

Bernard De Cuyper

Version:

1.15

Date:

02/05/2004

Remarks:

Tornado1 Iterative Linear Solver

 
Purpose:        CG for indefinte Linear systems(not always stable behaviour)
                Works on symmetric/indefinite matrices

                        Used to solve a set of linearized differencial equations,....

                        Some restoration are of the style: A * iNew = iOld
                        iNew could be X, and iOld could be b.
