Detailed Description
template<typename DERIVED>
template<int M>
class gtsam::Basis< DERIVED >::VectorEvaluationFunctor< M >
VectorEvaluationFunctor at a given x, applied to ParameterMatrix<M>. This functor is used to evaluate a parameterized function at a given scalar value x. When given a specific M*N parameters, returns an M-vector the M corresponding functions at x, possibly with Jacobians wrpt the parameters.

Calculate the M*(M*N) Jacobian of this functor with respect to the M*N parameter matrix P. We flatten assuming column-major order, e.g., if N=3 and M=2, we have H =[ w(0) 0 w(1) 0 w(2) 0 0 w(0) 0 w(1) 0 w(2) ] i.e., the Kronecker product of weights_ with the MxM identity matrix.
