| 摘 要： | 为了叙述方便,我们先引进拟置换矩阵和拟单位矩阵两个概念。定义1 设Q为n 阶矩阵。若Q的每行、每列恰好有一个元素为1或-1,其余元素全为0,则称Q为拟置换矩阵。定义2 n阶矩阵

| Abstract: | A matrix Q is called a (quasi) permutation matrix,
if everg row and every column of Q has exactlg one-zero entry (1 or
--1) 1. This paper presents a number of properties of quasi-permuta-
tion matrix and some properties of permutation matrix, and we point
out that an exercise in 3] is mistaken. |
