WebFor a real-valued differentiable function f: R n → R, the Hessian matrix D 2 f ( x) is the derivative matrix of the vector-valued gradient function ∇ f ( x); i.e., D 2 f ( x) = D [ ∇ f ( x)]. ∇ f ( x) is just an n × 1 matrix consisting of ∂ f / ∂ x 1, ∂ f / ∂ x 2, …, ∂ f / ∂ x n. Then D [ ∇ f ( x)] must be a 1 × n matrix. http://lowin.com.au/how-are-hessian-fabrics-produced.html
