摘要
本文利用矩阵的稳定值，给出泛正定阵的等价条件，进一步得到泛正定阵与广义正定阵之间的一些关系．
In this paper,using eigenvalues of matrix,we obtain some necessary and sufficient conditions on universal positive definite matrices.Further,we obtain relationship between generalized positive definite matrices and universal positive definite matrices.
