Detailed Description

template<typename FunctorType, typename Scalar = double>
class Eigen::HybridNonLinearSolver< FunctorType, Scalar >

Finds a zero of a system of n nonlinear functions in n variables by a modification of the Powell hybrid method ("dogleg").

The user must provide a subroutine which calculates the functions. The Jacobian is either provided by the user, or approximated using a forward-difference method.
