摘要
简要讨论了T-限制加权Drazin逆的性质,给出了T-限制加权Drazin逆收敛的充分必要条件,选取了合适的初始值,利用迭代方法计算T限制加权Drazin逆.最后,利用了数值例子进行说明.
In this paper, we establish a iterative method for computing T-restricted weighted Drazin inverse of A,and give necessary conditions for iterative convergence to the T-restricted weighted Drazin inverse.Moreover,we investigate a general choice of initial matrix in the it- erative methods for computing T-restricted weighted Drazin inverse.
