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.
