Preconditioned AOR iterative methods for \(M\)-matrices
The authors present general preconditioners for solving linear systems with a non-singular \(M\)-matrix. Additionally, they prove that the proposed preconditioners increase the convergence rate of accelerated overrelaxation (AOR) iterative methods. Finally, the authors demonstrate the applicability by solving a convection-diffusion equation and numerical results for the restarted generalized minimal residual (GMRES) method and precondiotioned restarted GMRES method are presented, using MATLAB.
