Linear systems with M-matrices often appear in a wide variety of areas. In this paper, we give general preconditioners for solving the systems with nonsingular M-matrix. We show that our preconditioners increase the convergence rate of AOR iterative methods. Numerical results for corresponding preco
The standard implementations of iteratike solvers for finitc elcment and finite difercnce mcthods frequently use a diagonal (Jacobi) preconditioncr, particularly for element-by-element schemes. However, for such methods the actual order of the condition number with respect to mesh size is not reduce
