The Semi-convergence of GSOR-like Methods for Singular Saddle Point Problems
- 83 Downloads
In this paper, we prove the semi-convergence of the class of GSOR-like methods with two real functions applied to solve the singular saddle point problems, and discuss the optimal iteration parameters and the corresponding optimal semi-convergence factor for methods in the class.
