The convergence of the MKSOR method for a class of block two-by-two linear systems
Jin Song Xiong · 2021
In this paper, the sufficient and necessary conditions for the convergence of the MKSOR method are given for a class of block two-by-two linear systems when the eigenvalues of the iterative matrix of Jacobi method are real or pure imaginary. And new results expanding the range of the convergence for the MKSOR method. Numerical experiments show that the effectiveness of new theoretical results.
