K-行正交矩阵的几点性质

Some properties on K-row orthogonal matrix

给出行(列)对称矩阵、K-行正交矩阵以及K-行对合矩阵的概念,研究了K-行正交矩阵的一些性质,得到K-行正交矩阵是行列对称矩阵以及它本身、它的行转置和列转置矩阵都是可逆矩阵等结论.同时,也研究了行对称矩阵与K-行正交矩阵、K-行对合矩阵的关系,并加以理论证明.

To travel（column） matrix,rows and rows of orthogonal matrix concept of co-matrix to study the lines of some simple properties of orthogonal matrix,the following conclusions： K-row orthogonal matrix is the ranks of the symmetric matrix,and so on.The author studied the row of symmetric matrices and the K-row orthogonal matrix,K-row matrix on the joint relationship and to be proved as well.
