摘要
该文运用块对角占优矩阵的性质,得到了解线性方程组的块Ja-cobi迭代和块Seidel迭代收敛的充分条件,并举例说明。
Some properties of block diagonally dominant matricesare used in this paper to obtain the sufficiet condition of the conver-gence of the block Jacobi iterative method and the block Seidel itera-tive method for linear equations. The example is taken to show it'sapplication.
