对两个实矩阵的左半张量积为正定矩阵的情况进行了研究,从特征值的角度给出了某些实矩阵的左半张量积为正定矩阵的一系列充要条件,并得到了一些相关结论.
The conditions that the left semi-tensor product of two real matrices is a positive definite matrix are researched,and a series of necessary and sufficient conditions are given from the perspective of eigenvalue. At the same time,some correlative results are obtained.
