A new preconditioned Gauss-Seidel method for linear systems

Bing-Yuan Pu, Chun Wen


In this paper, a new preconditioner is introduced to improve the convergence rate of the Gauss-Seidel iterative method in linear systems, and some comparison theorems are derived. Numerical examples demonstrate the efficiency of the proposed method.
