摘要
考虑分块矩阵和矩阵运算中的常见秩不等式的取等条件,利用分块矩阵的初等变换给出了若干秩不等式取等的充要条件.
Conditions of the equlity signs for some common rank inequalities of matrices which appear in block matrices and the matrix operations are studied. The necessary and sufficient conditions of equlity signs for some matrix rank inequalities are given by using the elementary transformation of block matrices.
