Inheritance diagram for F_QmrCgStab2LS:
Purpose: QmrCgStab2 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. QmrCgStab2 is a QmrCgStab with omega computed differently. omega is computed to make r more orthogonal to s, making chance to get true minimization of the residu.
