矩阵分块的Jacobi迭代收敛的几个准则

SOME CONVERGENCE CRITERIA OF JACOBI ITERATION FOR BLOCK MATRIX

在文[1],[2],[3]中,先后讨论了分块矩阵的度量性质及矩阵分块的迭代法的收敛性.本文给出了矩阵分块的 Jacobi 迭代收敛的两个新的判别法及其敛速估计.

In this paper we give out two new estimative methods of convergence of Jacobi itera- tion for block matriy and the estimates of convergence speed.
