On Some Properties of the Generalized Positive Definite Matrix

讨论了广义正定矩阵的一些性质，并给出一类较特殊的广义正定矩阵，它的多个自身的Ｈａｄａｍａｒｄ积仍保持广义正定性的一个充分条件。

Some properties of the generalized positive definite matrix are discussed. A class of more particular ones is given. It is shown that its multiple self Hadamard product still maintain a sufficient condition of generalized positive definiteness.
