Webfminunc is for nonlinear problems without constraints. If your problem has constraints, generally use fmincon. See Optimization Decision Table. example x = fminunc (fun,x0,options) minimizes fun with the optimization options specified in options . Use optimoptions to set these options. example WebYou should be able to use 'fmincon' in the following syntax: x = fmincon (fun,x0, [], [], [], [],lb, [],nonlcon) x0 is a three element vector and the result will also be in the same format which will give you the values for x,y and z. Take a look at the documentation of fmincon for more details: http://www.mathworks.com/help/optim/ug/fmincon.html
