摘要
当线性方程组的系数矩阵A是严格对角占优阵、不可约弱对角占优阵、M阵、H阵和Stieltjes阵时,本文改进了M.Martins论文中MSOR迭代法收敛性的一些结果。
When the coefficient matrix A of a linear system is a strictly diagonally dominant, irreducible weakly diagonally dominant, M, H, or Stieltjes matrix, some results on the convergence of the MSOR method in the paper written by M. Martins are improved.
