Is there any reason that wasn't being done, e.g., that code is broken? There are a number of function definitions for hessian in derivative.jl that have no gradient argument and create one numerically.
Webwhere the n×n Hessian matrix H is assumed to be symmetric, A is an m×n sparse matrix, c ∈Rn, b ∈Rm, l ∈Rn, and u ∈Rn. Elements l j and u j may be taken as −∞or +∞if no bounds are present for these variables, and l j = u j if fixed variables are present. We assume that A is of full rank. In practice, it may be necessary to apply ...
