中文摘要
      当前,在解代数Riccati方程的各种方法中,Schur向量法是一种相当有效的算法。Schur向量法的关键在于交换伪上三角形矩阵对角线上的对角块的位置。以前,均使用EXCHNG程序来实现这一交换过程。它用的是QR方法,因而占用了很大一部分计算时间。本文提出用一种直接方法来实现这一交换,可节省一些计算时间。
英文摘要
      There are many kinds of methods to solve algebraic matrix Riccati equation. Of these methods, the Schur method is quite efficient one. The key of Schur method is to exchange the diagonal blocks in the upper pseudo-triangular matrix. In literature, usually use Programme EXCHNG to implement this requirement. It uses QR iteration method, so that spends a lot of computing time. In this paper, a kind of direct method for exchanging two diagonal blocks is given and it can save some computing time.
