WebAs a preliminary answer, the first warning tells you that the Trust-Region algorithm can't solve this problem. You should change the algorithm using optimoptions: options = optimoptions (@fmincon,'Algorithm','sqp',) for instance (choose the algorithm here) – Etienne Pellegrini Aug 21, 2014 at 4:22 Yes! This was left out of my sight! Webfmincon uses one of four algorithms: active-set, interior-point, sqp , or trust-region-reflective. Choose the algorithm at the command line with optimoptions. For example: options = optimoptions ( 'fmincon', 'Algorithm', 'active-set' ); The default trust-region-reflective requires: A gradient to be supplied in the objective function
