Detailed Description

Symmlq 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.
                
                Symmlq has some limitations, see paper.
