摘要
给定半正定矩阵B,考虑矩阵可交换问题A惨BA=ABA惨.运用矩阵分解的方法,给出了满足上述要求的矩阵的一个充要条件.
Consider the changeable matrices problem as the form A~ㄒBA=ABA~ㄒ for the given positive semi-definite real matrix B.By the method of matrices decomposition,a sufficient and necessary condition to satisfy the above requirement is obtained.
