Английская Википедия:Copositive matrix
Материал из Онлайн справочника
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.
