Yang Zhong-peng · Journal of Putian University · 2005
First,we point out that the proof of the Hadamand inequality of positive definite matrix in Ding Weiping's paper Proof of an inequa lity of positive definite matrix is not proper.Then according to the tra in of thought and using the property of positive definite matrix we present a proper proof.
