virtual gsl::matrix hessian() const
virtual gsl::vector gradient() const
Base class for derivative estimates with Hessian.
void setVector(gsl::vector const &vector)
Set a vector and compute function value, gradient and Hessian efficiently.

This class has two purposes.
Namespace for functions that can be used by ipo::Objective and ipo::Constraint.
This class computes a function at a vector.
