gtsam::Basis< DERIVED >::DerivativeFunctor Class Reference

Detailed Description

template<typename DERIVED>
class gtsam::Basis< DERIVED >::DerivativeFunctor

An instance of a DerivativeFunctor calculates f'(x;p) at a given x, applied to Parameters p.

When given a scalar value x and a specific N*1 vector of Parameters, this functor returns the scalar derivative value of the function at x, possibly with Jacobians wrpt the parameters.
