| Abstract: | The necessary and sufficient condition of convergence of several iterative methods for computing the generalized inverse A (2) T,S is presented.It is proved that the iterative methods converge to the generalized inverse A (2) T,S if and only if these conditions are satisfied.Also, the initial conditions of the iterative methods are considered. |
