摘要
利用矩阵的Moore-Penrose逆与不相容线性方程组的极小范数最小二乘解的关系,导出了分块矩阵[A,B]的Moore-Penrose逆[A,B]+的显式表示.
By using the relation of the Moore-Penrose inverse of matrices and the unique minimum-norm leastsquare solution of the inconsistent linear system, the explicit expression for the Moore-Penrose inverse of a columnwise partitioned matrix[A ,B] is deduced.
