Some Properties and Determination of Complex
Metapositive Subdefinite Matrix, Yuan Lü · 2009
In this article, we introduced the concept of complex metapositve subdefinite matrix, studied its properties and subeigenvalue, put forward some necessary and sufficient conditions that the complex matrix was the complex metapositive subdefinite matrix, and obtained the positive definiteness of the metapositve matrix which is subcongruent to the complex metapositive subdefinite matrix.
