These properties are similar to properties of positive semi-definitematrices and positivedefinitematrices.
这些性质类似于通常的半正定矩阵及正定矩阵的性质。
2
Some equivalent representations of complex positive semi definitematrices are given by using equivalent conditions of positive semi definite of real symmetric matrix.
利用实对称矩阵的半正定之等价条件给出了复正半定矩阵的几个等价条件。
