Yuan Lü · Journal of Mathematics Research · 2009
In this article, we introduced the concept of complex metapositve subdefinite matrix, studied its properties andsubeigenvalue, put forward some necessary and sufficient conditions that the complex matrix was the complexmetapositive subdefinite matrix, and obtained the positive definiteness of the metapositve matrix which is subcongruentto the complex metapositive subdefinite matrix.
