Inheritance diagram for F_MgcrLS:
Purpose: Mgcr(m) krylov solver with restart each m iterations, for non symmetric/indefinite linear system Used to solve a set of linearized differencial equations,.... Mgcr is a Krylov solver working on residuals. It approximates a solution via generation of the suitable partial Krylov orthonormal base, especially in the restart case. We hope that a small number of Krylov sub-spaces are sufficient to lead to a good solution. Mgcr is slightly faster than GMRES, it is also much less expansive that CGR. Mgcr need only to solve a upper triangular, and is not requiring to solve a minimisation. It does not breakdown, unless he found the exact solution!
