Detailed Description

Minres Linear Solver.

Author:
Bernard De Cuyper
Version:
1.15
Date:
02/10/2004
Remarks:
Tornado1 Iterative Linear Solver
 
Purpose:        Solve symmetric indefinite Linear Systems. 
                Uses a combined  reduced Krylov and least square approach.
                
                Minres has some limitations, see paper. Symmlq may less expensive too.
