摘要 研究矩阵方程组AX=B,XC=D的Hermitian反自反(反Hermitian反自反)最小二乘解.利用分块矩阵和Hermitian反自反(反Hermitian反自反)矩阵的性质,得到了解的一般表达式,并研究了与其相关的任意给定矩阵的最佳逼近问题. Hermitian anti-reflexive (anti-Hermitian anti-reflexive) least squares solutions of matrix equations AX = B, XC = D were considered. With special properties of partitioned matrices and Hermitian anti-reflexive (anti-Hermitian anti-reflexive) matrices, the general expression of the solution was obtained. Moreover, the related optimal approximation problem to a ~iven matrix over the solution set was considered.
