Yang Wen-qi · Xi'an Gongcheng Keji Xueyuan xuebao · 2012
To further study the relationship between linear transformations and matrices,the positive definite transformation and positive semi-definite transformation are introduced.The relation between the positive(semi-) definite transformation and the positive(semi-) definite matrix are given.The equivalence conditions and some properties of the positive definite transformation and positive semi-definite transformation are discussed.
