WebFeb 12, 2011 · Accepted Answer. That exit status means that it found a feasible point (according to the constraints) where the surface was flat to within the tolerance option. There might be a better point but the search algorithm cannot tell which direction it might lie in. Please remember that fmincon never promises the optimal solution, just a local optimum.

WebJun 6, 2013 · 1 Use the nonlcon parameter of fmincon (I'm assuming here your constraints are nonlinear?). Then A (X) and B (X) are fine but for C (X) it must be in the form c (X) < 0 so you'll need to break it into two constraints of that form. I pulled this example of how to specify a function for nonlcon from elsewhere in the documentation:
