正交矩阵的进一步推广及性质

Further Exteneing of the Orthogonal Matrices and Their Properties

本文将正矩阵的概念推广,引入列正交矩阵与行正交矩阵及亚正交矩阵的概念,并讨论了它们的性质。给出了用列正交矩阵化实对称矩阵为其惯性矩阵的结论。

By extending the concept of orthogonahthe column irthogonal matrices,the row orthogonal matrices and the quasi-orthogon onl matrices. And then their properties are discussed. In the end ,a con-clusion is given:An symmetrie real matrices can be transformed intoits inertial matrices can be transformed into its inertialmatrices by the column ovthogonal mathices.
