Detailed Description

QmrCgStab2 Linear Solver.

Author:
Bernard De Cuyper
Version:
1.15
Date:
08/07/2004
Remarks:
Tornado1 Iterative Linear Solver
 
Purpose:        QmrCgStab2 of nxn Linear Solver
                        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.

                QmrCgStab2 is a QmrCgStab with omega computed differently.
                omega is computed to make r more orthogonal to s, making chance to get true minimization of the residu.
