我们在这里介绍一种改进的广义连续过松弛(MGSOR)方法来求解增广线性系统。我们证明,对于三个参数的松散限制,MGSOR 方法收敛于线性系统的唯一解。最后,数值例子说明了 MGSOR 迭代方法的有效性,该方法优于改进的类 SOR 方法和广义连续过松弛方法。 参考文献 Z. Z. Bai,B. N. Parlett,Z. Q.

We introduce here a modified generalised successive over-relaxation (MGSOR) method to solve augmented linear systems. We prove that the MGSOR method converges to the unique solution of the linear system for a loose restriction on three parameters. Finally, a numerical example illustrates the effectiveness of the MGSOR iteration method which outperforms the modified SOR-like method and the generalised successive over-relaxation method.
