In mathematics, specifically linear algebra, a real matrix A is copositive if
for every nonnegative vector . The collection of all copositive matrices is a proper cone; it includes as a subset the collection of real positive-definite matrices.
. The collection of all copositive matrices is a proper cone; it includes as a subset the collection of real Copositive matrices find applications in economics, operations research, and statistics.
