| Abstract: | In this paper,some properties of N0-matrices are discussed on the basis of inequality for the Hadamard product of an M-matrix and an inverse M-matrix.At the same time,an estimate for the smallest eigenvalue of the Hadamard product of an N0-matrix and an inverse M-matrix is proved.In particular,If is an inverse N0-matrix,we obtain the estimation of the smallest eigenvalue in module. |
