#include <F_QmrCgStabLS.hpp>
Inheritance diagram for F_QmrCgStabLS:


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.
