摘要
从复矩阵的运算性质、矩阵为复正定矩阵的一些充分条件与充分必要条件、两个矩阵乘积为复正定矩阵的充分必要条件、两个矩阵的Hadamard乘积是复正定矩阵的条件及其相关性质4个方面研究了复正定矩阵的性质,共给出了有关的20个命题,并证明了其中部分结论,而另一部分结论的证明容易在相关文献中查到.
This paper attempts to study the following properties of the complex positive definite matrix including the operational property of the complex positive definite matrix as the sufficient and necessary c conditions of the complex positive definite matrix, the products of two matrixes as the sufficient and necessary conditions of the sufficient and necessary conditions of the complex positive definite matrix and Hadamard products of two matrixes as the conditions and the relative properties of the complex positive definite matrix. The author assigns 20 relative proposition in all and demonstrates some of the conclusion. It is easy to consult the demonstrations of the other conclusions in the relative documents.
