摘要
应用块拟对角占优矩阵的几个充分条件,研究块α-二重几何平均对角占优矩阵的非奇异性,特征值分布及以这类矩阵为系数矩阵的线性方程组的Jacobi迭代解法的收敛性等问题。
n this paper, firstly, several sufficient conditions for quasi -block diagonally dominant matrices are given. Then, by using these results, the nonsingularity, distribution of eigenvalue of blockdouble mean diagonally dominant matrices and the convergence of Jacobi iterative method for solving linear system are studied.
