摘要
非奇异H矩阵是一类应用较为广泛的特殊矩阵.根据非奇异H矩阵的性质,选取递进元素,构造正对角因子,得出非奇异H矩阵的几个新的判定条件,改进并推广相关文献的结果,并用数值例子说明该判定的优越性.
The nonsinggular H-matrix is a special class of matrices with wide applications.According to the properties of nonsingular H-matrix,we select progressive elements,structure positive diagonal factors,and obtain several new iterative criteria of nonsingular H-matrices,which improve and extend some related results.Effectiveness of such criteria is illustrated by a numerical example.
