Inheritance diagram for F_BiCgStabLS:
Purpose: Bicgstab is a simple stabilized CGS, used in non-symmetric/(indefinite) matrices 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. Paper: "Reliable updated residuals in hybrid Bi-CG methods", G. L.G.
