线性方程组的预条件比较定理
comparison theorem for the iterative method with the new preconditioner (I + S1)
在这篇文章中,我们提出了一种新的预条件,并且分析了它的收敛性和比较定理,最后,数值例子也说明了这种预条件的有效性.
In 1991, Gunawardena et al.(Linear Algebra Appl. 154–156(1991)123) have reported the modified Gauss–Seidel method with a preconditioner (I + S). In this article, we propose to use a preconditioner (I + S1) instead of (I + S). we get the comparison theorem for the proposed method and show that the new method is greater than MGS. Simple numerical examples are also given.
