newton solver implementations

Functions
template<int N, typename FUNC >
EIGEN_DEVICE_FUNC int	newton_solver (Eigen::Matrix< double, N, 1 > &X, FUNC functor, double eps=EPS, int max_iter=MAX_ITER)
	Newton method with user-provided Jacobian. More...
template<int N, typename FUNC >
EIGEN_DEVICE_FUNC int	newton_numerical_diff_solver (Eigen::Matrix< double, N, 1 > &X, FUNC functor, double eps=EPS, int max_iter=MAX_ITER)
	Newton method without user-provided Jacobian. More...
template<typename FUNC , int N>
EIGEN_DEVICE_FUNC int	newton_solver_small_N (Eigen::Matrix< double, N, 1 > &X, FUNC functor, double eps, int max_iter)
	Newton method template specializations for \(N <= 4\) Use explicit inverse of F instead of LU decomposition. More...
