Some Properties and Determination of Complex Metapositive Subdefinite Matrix

  •  Yuan Lu    


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.
