Gradient Of Quadratic Form - 68.2 gradient of the quadratic form. For x ∈ rn and a ∈ rn × n let: F(g(x), h(x)) = g(x), h(x) = gt(x)h(x) where: In mathematics, a quadratic form is a polynomial with terms all of degree two (form is another name for a. In section 41.1.2 we define the partial derivatives ( 41.23) and gradient ( 41.29) of a multivariate function (. The idea of quadratic forms is introduced and used to derive the methods of steepest descent, conjugate directions, and conjugate gradients. Quadratic form as f(x) = f(x 1;x 2;x 3) = [x 1 x 2 x 3] 2 6 4 a 11 a 12 a 13 a 21 22 23 a 31 a 32 a 33 3 7 5 2 6 4 x 1 x 2 x 3 3 7 5= xax; From the definition of f, it is obvious that f(g(x), h(x)). G(x) = x h(x) = ax.
