针对两个矩阵和Drazin逆的表示,由Drazin逆的定义,根据矩阵分解的思想,利用Drazin逆的相关性质,给出了两个矩阵的和在一定条件下Drazin逆新的表示.新结果推广了现有的一些结果.
According to thinking of matrix decomposition,the representations for the Drazin inverse the sum of two matrices are given using the properties of Drazin inverse.The new results generalize some existing results.
