研究了权矩阵为可逆阵的矩阵乘积的加权广义逆。在已有的加权广义逆矩阵存在条件及表达式的基础上,利用矩阵的秩,给出了2个及3个矩阵乘积的加权广义逆的几个表达式。
研究瞭權矩陣為可逆陣的矩陣乘積的加權廣義逆。在已有的加權廣義逆矩陣存在條件及錶達式的基礎上,利用矩陣的秩,給齣瞭2箇及3箇矩陣乘積的加權廣義逆的幾箇錶達式。

This paper discusses the weighted generalized inverses of the matrices products where the weights are invertible.Based on the condition for the existence of weighted general-ized inverse of a matrix and its expression,several expressions for the weighted generalized in-verses of two and three matrices products are given by using rank of matrix.
