Hi, I have defined a tensor like presented in the documentation: ``` function tensor(f, x) n = length(x) out = ForwardDiff.jacobian(y -> ForwardDiff.hessian(f, y), x) return reshape(out, n, n, n)...

Hi! I am trying to get Hessian-vector product, without having to explicitly compute the Hessian matrix. I have the following example: ``` using ReverseDiff function f(x) m = length(x) return...

Time to compute gradient is too long

Hi, I don't know if this is a real issue or more of a problem with my understanding of automatic differentiation. I was doing some simple benchmarking with ReverseDiff. From...

Wrong roots with multroot

Hi! I've had issues with the multroot function. I have the function f(x)=1.7273219441449328e-6+257.8444185695129*x+111.17574047075945*x^2 the roots for this polynomial function should be: -2.31925 and -6.699e-9 but if I do : `using...

Hi, Sorry to create another issue with an easy question, but I was wondering if there is a way to display each iteration of a line search algorithm. The basic...
