摘要
矩阵的秩是矩阵重要的数字特征之一,在代数研究中有着重要的作用,它与线性方程组、线性空间等都有着密切的联系.因而,了解矩阵的秩可为更好地学习、研究代数打下基础.本文讨论了矩阵秩的一些常见不等式.
Matrix rank, one of the important numerical characteristics of matrix, plays an important role in algebra. It has a close relation to linear equations and linear space. The study of matrix rank can lay a foundation for the further study and research of algebra. Hence, it is necessary to discuss some common inequalities of matrix rank.
