奇异值分解中非奇异矩阵的性质结构

On the Structures of the Nonsingular Matrices of QQ-SVD

矩阵分解在和矩阵理论中有着极其重要的作用,其中奇异值分解尤其重要.本文着重研究了三个矩阵QQ-SVD分解中非奇异矩阵的性质结构.

Matrix deomposition plays an important role in the study of matrix theory, especially singular value decomposition（SVD）. In this article we study the structures of the nonsingular matrices of the multiple quotient singular value decomposition QQ-SVD.
