In mathematics, specifically linear algebra, a real matrix A is copositive if

<math>x^TAx\geq 0</math>

for every nonnegative vector <math>x\geq 0</math>. The collection of all copositive matrices is a proper cone; it includes as a subset the collection of real positive-definite matrices.

Copositive matrices find applications in economics, operations research, and statistics.
