摘要
本文给出广义置换矩阵的若干性质,证明了广义置换矩阵即是非负的所谓广义正交矩阵,并且讨论了方程AX=b当A为广义置换矩阵时的一个迭代收敛问题.
In this paper, some properties of a generalized permutation matrix are given. It is shown that the generalized permutation matrix is a non-negative generalized orthogonal matrix. Then, an iterative covergence problem of the equation AX=b is discussed, where A is a generalized permutation matrix.
