一组非奇异H-矩阵的新判据

Some New Criteria for Nonsingular H-Matrices

利用α-对角占优矩阵的元素性质和不等式性质,通过添加适当的参数,给出了一组非奇异H-矩阵的判定条件,并用数值实例验证了判定方法的有效性.

By making use of the element properties ofα-diagonally dominant matrix and adding the appropriate parameters,we present a set of determination conditions for nonsingular H-matrix and verify the effectiveness of the method by numerical examples.
