Hi all, I have a function obj(p) that solves for the parameter t of a Bezier curve B(t) so that the arclength is equal to some arbitrary value (2 in this kind-of-minimal example). It uses the Newton’s method. The Bezier curve is parametrized by 4 3D points, so that the input vector p has 12 elemen…

Custom rule for differentiating through Newton solver using ForwardDiff: works for gradient, fails for hessian

I do not understand what you mean. Do you say that you implemented the hessian of the function defined by the implicit function theorem?
