I'm given that if A is a fixed p × p real matrix, and x is a p -dimensional real vector, and if f ( x) = x T A x, then ∂ f ( x) ∂ x = A x + A T x = ( A + A T) x which is p × 1 dimensional real vector. Web17 de set. de 2024 · Definition 7.2.11. A symmetric matrix A is called positive definite if its associated quadratic form satisfies qA(x) > 0 for any nonzero vector x. If qA(x) ≥ 0 for nonzero vectors x, we say that A is positive semidefinite. Likewise, we say that A is negative definite if qA(x) < 0 for any nonzero vector x.
