| Abstract: | The characteristics of positive definiteness of atrix has been an interesting problem to us. Recently,judging the necessary and sufficient condition of the characteristics of positive definiteness to a matrix has been published on some publications one by another. This paper gives out a sufficient rule about how to judge the positive definiteness of a real square matrix. Applying this sufficient rule we can also prove two principles about judging the characteristics of positive definiteness of Hadamard product. |
