Detailed Description

QmrCgStab Linear Solver.

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

                Use quasi-minimization of the residu, the use of QMR allows somewhat faster and 
                smoother convergence that freun TFQMR and Bi-CgStab.
