Abstract:In this paper,by using matrix iterative analysis and comparison theorems,make an improved SOR iterative method to solve the large linear system in preconditioned based on matrix splitting,then prove the improved method not only to accelerate the SOR iterative method,but also to excel the general preconditioned SOR method.Last the numerical example is given.
Keywords:precondition  convergence  the SOR iteration method  spectral radius
