The survey of preconditioners used for accelerating the rate of convergence in the Gauss–Seidel method

摘要

Several preconditioned iterative methods reported in the literature have been used for improving the convergence rate of the Gauss–Seidel method. In this article, on the basis of nonnegative matrix, comparisons between some splittings for such preconditioned matrices are derived. Simple numerical examples are also given.
