Iterative methods for linear equations

WebAbstract. Recently, Tian et al. [Computers and Mathematics with Applications, 75 (2024): 2710-2722] came up with the inner-outer iterative method to solve the linear equation and studied the corresponding convergence of the method. In this paper, we improve the main results of the inner-outer method and get weaker convergence results. WebITSOL , Iterative Solution module (now includes Zitsol the complex variant).
