K-对角占优矩阵

K-DIAGONALLY DOMINANT MATRICES

提出Ｋ－对角占优矩阵，它是连对角占优矩阵及某些Ｈ－矩阵判别法的推广，讨论了其基本性质以及与Ｈ－矩阵的关系，并给出其一些应用．

おn this paper, we propose Kdiagonally dominant matrices, it is a generalization of double diagonal lgdominant matrices and some sufficient conditions of Hmatrices. We discuss its basic properties and the relations with Hmatrix, and give some applications.
