【Abstract】 The theory of diagonally dominant matrices is important in numeral analysis and matrix theory. In this paper , we introduce the concept of two classes of generalized diagonally dominant matrices, their spectral properties are studied , and practical sufficient conditions of H matrices are obtained also.更多还原
