Hi guys, Im trying to use the LMSolver (Levenberg-Marquardt Algorithm) but I cant find any example online and I dont really understand the documentation.

@berak Im trying to estimate facial expresisons using Candide3 model wich has multiple variables, so my idea is to use the 2D projection of the facial model and with LMSolver find the variables that fit better and minimize error
