摘要
建立了作为广义正定矩阵的复正定矩阵的一些基本性质,总结并给出了实对称正定矩阵、Hermite正定矩阵、亚正定矩阵和复正定矩阵4类正定矩阵之间的相互关系.
In this paper, we give several basic properties of complex positive definite matrices regarded as generalized positive definite matrices, and show the relationship among four types of positive definite matri- ces, i. e., real symmetric positive definite matrices, Hennitian positive definite matrices, metapositive deft- nite matrices and complex positive definite matrices.
