摘要
讨论了分块初等变换的相关的概念和性质.采用分块初等变换的方法,对有关矩阵的秩的和的等式的问题进行了研究.研究中把推理过程计算化,使得这类问题的解决过程整齐划一,简单明了.
In this paper,the conceptions and properties of elementary transformations of a partitioning matrix is discussed.With the method of elementary transformations of a partitioning matrix,the problem about the equation of ranks of matrices is studied.The simple processes of the proofs are integrated into calculations in the study.
