Abstract
Based on the concept of diagonally dominant matrices, by compared with the elements of a matrix, by means of some methods in matrix theory and inequality of scaling techniques, the corresponding positive diagonal matrix was constructed, a new sufficient condition to determine nonsingular H-matrices was given and the corresponding results were improved. Thus the applicability of the theorem is remarkably expanded. The advantages were illustrated by a numerical example.关键词
