1. 简介。在本文中,我们将考虑循环雅可比方法的收敛问题。在2中,我们证明某些不同的循环排序在某种意义上产生完全相同的结果。在第3部分中,我们讨论了雅可比方法是否对任意循环排序产生收敛的问题。在第四部分中,我们认为某些循环排序将导致比其他循环排序更高的收敛速度,并且提供了实验证据来支持这一论点。为了节省空间,将假定渲染器熟悉 Jcobi 方法,以便最小化定义和解释的数量。不熟悉这些方法的读者应查阅本文末尾列出的参考文献之一([6] 除外)。再次为了节省空间,将直接参考[7]中的方程。带有n星号的方程编号指的是[7]的n个方程。
1. Introduction. In this paper, we shall consider the question of con-vergence for cyclic Jacobi methods. In 2, we show that certain different cyclic orderings produce exactly the same result ina certain sense. In 3, we discussthe question of whether a Jacobi method produces convergence for an arbitrary cyclic ordering. In 4, we argue that certain cyclic orderings will result in higher rte of convergence thn others nd experimental evidence is presented to support this rgument. To conserve spce, it will be ssumed the reder is fmilir with Jcobi methods so that the number of definitions nd explanations cn be minimized. Readers not familiar with these methods should consult one of the references (except [6]) listed at the end of this pper. Again to conserve spce, direct reference will be mde to equations in [7]. An equation number mrked with n steriskrefers to n equation of [7].
