Can you provide good references to the trust region dogleg method? This optimization method is used in Matlab's
fsolve to solve nonlinear simultaneous equations and I want to understand it better.
I have noticed the list of references at the bottom of the Matlab help page but I'm lookng for something that gives a gentler introduction: more intuitive, not too mathematical and preferably with diagrams. I have a background in quantum physics, but am not so strong on numerical math.
