I could rewrite … Web23 jun. 2016 · The apparent fix would be to send it to finite_difference_hessian{T <: Number}(f::Function, x::Vector{T}) instead. 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.
