摘要: 利用α-对角占优矩阵理论对矩阵的行指标集进行细分, 通过构造递进迭代系数构造正对角矩阵, 给出广义严格α-对角占优矩阵的判定条件, 得到了非奇异H-矩阵的细分迭代判定准则. 数值实例表明, 所给判定准则有效.

关键词: 非奇异H-矩阵, -对角占优矩阵, 判定准则, &alpha

Abstract: Some subdivided line index sets of the matrix were given by using the theory of α-diagonally dominant matrices. A positive diagonal matrix was constructed by constructing iterative coefficients. Some determination conditions of generalized strictly α-diagonally dominant matrices were given, and some subdivided iterative criteria for nonsingular Hmatrices were obtained. Numerical examples show that the given criteria are effective.

Key words: nonsingular Hmatrix, αdiagonally dominant matrix, criteria
