摘要
本文讨论了求解Sylvester方程AXB+CX=D的OROD迭代法(正交残量法和正交方向迭代法)的几个重要性质,证明了该算法产生的误差序列是单调递减的,同时给出了该算法的最小化性质的精确刻画,最后给出了一些数值例子.
This paper presents several properties of the OROD iterative method (orthogonal residual method and the orthogonal direction method) for solving the Sylvester equation AXB + CX = D. It is showed that the corresponding error sequence decreases monotonely. The minimization property of the method is precisely characterized. A numerical example is presented in the end.
