摘要
通过引入反对称矩阵的导出矩阵和次导出矩阵的概念,给出n阶反对称矩阵与n阶对称矩阵可交换的充要条件,利用导出矩阵和次导出矩阵的秩,对3阶反对称矩阵进行分类。
In this paper,we introduce the concepts of the induced matrix and sub-induced matrix of an anti-symmetric matrix,and give two equivalent conditions that an n-order anti-symmetric matrix and an n-order symmetric matrix are commutative.At last,using the ranks of induced matrix and sub-induced matrix,we give a partition of 3-order anti-symmetric matrices.
