关于“一类矩阵秩的恒等式及其推广”一文的注记

Remarks on “Rank Identies of a Class of Matrices with their Generalization”

用广义初等变换得到了一个关于矩阵的秩的恒等式,并将其推广到一般情形,该结果能把文[2]及有关文献的结论统一起来,同时给出了文[2]中猜想成立的一个充分条件。

In this paper, a rank identities of matrices is obtained by generalized elementary transformation .This main result generalizes the conclusions of[2]. Moreover, We give a reply on a hypothesis in[2].
