A Minimal Residual Method for Shifted Skew-Symmetric Systems
Reijer Idema, C. Vuik · Research Repository (Delft University of Technology) · 2007
We describe the MRS 3 solver, a Minimal Residual method based on the Lanczos algorithm that solves problems from the important class of linear systems with a shifted skew-symmetric coefficient matrix using short vector recurrences.The MRS 3 solver is theoretically compared with other Krylov solvers and illustrated by some numerical experiments.
