摘　　要：判定一个矩阵是否为非奇异H矩阵,一般采用矩阵右乘1个正对角矩阵的方法,但由于矩阵左边乘1个正对角矩阵并不改变其占优性,因此采用矩阵左右同时乘以不同的正对角矩阵的方法,获得到了非奇异H矩阵的一组充分条件,实例说明所得结果是有效的﹒Determining whether a matrix is a nonsingular H-matrix, the general method is right multiplied the matrix by a positive diagonal matrix, since the left multiply a matrix by a positive diagonal matrix does not change its dominance, a set of sufficient conditions for nonsingular H-matrix is obtained by left multiply and right multiply the matrix by a different positive diagonal matrix respectively, and the examples show that the results are effective.

关 键 词：严格对角占优矩阵 M矩阵 非奇异H矩阵
