Hessian evaluation.
Compute the hessian, has to be implemented in concrete classes. The hessian is computed for a specific sub-function which id is passed through the functionId argument.
hessian | hessian will be stored here |
argument | point where the hessian will be computed |
functionId | evaluated function id in the split representation |
