But the help files say that fsolve uses the "Trust-Region Dogleg Method" by default. So is there nothing more I can do? Am I already using the T-R Dogleg Method? I really need to solve these equations. my m file is functionF = moments5(x) ...

In this paper, the particular solution technique for inverse simulation applied to the quadrotor maneuvering flight is investigated. The trust-region dogleg (DL) technique which is proposed alleviates the weakness of Newton's method used for numerical differentiation of system states in the solution pr...

In this paper, the dogleg routine is exploited in the process of optimization to obtain valid trust region steps. The proposed method is compared with sensitivity technique via several RF/microwave components. 2012 Wiley Periodicals, Inc. Int J RF and Microwave CAE, 2013.doi:10.1002/mmce.20690...
A quadratic approximation via a Quasi-Newton approximation of the Hessian matrix is used to replace the inverse matrix of Hessian matrix; (ii) The Dogleg method is used to define the step size; and (iii) The adaptive change of the step size is adjusted by the classical trust region constrai...
