摘要
利用对角占优矩阵理论,通过对矩阵行、列指标集的划分,给出了一组非奇异H-矩阵的充分条件,数值例子表明判定准则是有效的.
By using the theory of diagonally dominant matrices, we partition the row and column index set of square matrix, then obtain sufficient conditions of a set of nonsingular H-matrices. Finally, an example is presented to illustrate the effectiveness of the proposed criteria.
