摘要
给出了块严格α-双对角占优矩阵的等价条件,得到了块H-矩阵的实用判定方法.作为应用,给出了矩阵非奇异性的新判据,并通过数值示例验证了结果的有效性.
Equivalent representations of block strictly α-double diagonally dominant matrices are given.As an application,we obtain some criteria for block H-matrices and nonsingular matrices.Advantages of the results obtained are illustrated by a numerical example.
