摘要
复正定矩阵是Hermite正定矩阵的推广。文章在已有的Kronecker积性质的基础上,利用矩阵的特征值,讨论了复正定矩阵的Kronecker积的正定性,给出了两个复正定矩阵的Kronecker积仍是复正定矩阵的一个充要条件。
The complex positive definite matrix is Hermitian positive definite matrix of generalize. Based on the well - known properties of the Kronecker product, the positive definiteness of Kronecker product of complex positive definite matrices are discussed by using eigenvalue of matrices in this paper. A necessary and sufficient condition for the Kronecker product of two complex positive definite matrices to be complex positive definite is given.
