The Extension of Real Sub-symmetric Matrix and Sub-symmetrical Transformation Transformation

摘要: 一方面用较简便的方法证明实次对称矩阵的若干性质,并进行一些推广,另一方面对次对称变换进行探究,得到次对称变换的若干性质,并将次对称矩阵和次对称变换统一起来,具有一定的理论价值与实践意义.

Abstract: Abstract:On the one hand，some properties of real sub-symmetric matrix are proved with a simple method, and some extension is made accordingly. On the other hand，Sub-symmetric transformation is discussed，and several properties of sub-symmetric transformation are obtained, and real sub-symmetric matrix and sub-symmetric transformation are unified, which is of certain theoretical and practical value.
