A **copositive matrix** is a special type of matrix that arises in the context of optimization and mathematical programming, particularly in the study of quadratic forms and convexity. A symmetric matrix \\( A \\) is said to be copositive if for any vector \\( x \\) in the non-negative orthant \\( \\mathbb\{R\}^n_+ \\) (i.e.
