摘要 结合矩阵分裂理论及比较定理,给出一种改进矩阵分裂形式的预条件含参数SOR迭代方法,证明这种方法不仅能加速SOR迭代法的收敛性,而且优于一般的预条件方法,并找出参数的最优选取.最后通过数值例子加以说明. 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.
