Regularized iterative method for ill-posed linear systems based on matrix splitting

In this paper, the concept of matrix splitting is introduced to solve a large sparse ill-posed linear system via Tikhonov?s regularization. regularization process, we convert well-posed system. The convergence such discussed by using different types splittings. Comparison analysis both systems are studied operating certain weak Further, have extended double [Song J. and Song Y, Calcolo 48(3), 245-260, 2011] type II for nonsingular symmetric matrices. addition that, some more comparison results presented with help splittings I II.
