摘要
n阶全阵环存在零因子 ,本文给出了零因子存在的充要条件 ,并借助于广义逆矩阵 ,得出了零因子的计算公式 ,进而找出零因子。
Nought factor exist in ring of total matrix of n step.In this paper the mecessary and sufficiemt conditions were given.By using generalized inverses of matrix,the calculating formula was worked out and the nought factor was found out.
