Webflf is the exit flag. An exit flag of 1 indicates xf is a local minimum. of is the output structure, which describes the fminunc calculations leading to the solution. patternsearch To solve the optimization problem using the patternsearch Global Optimization Toolbox solver, enter: 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. great clips rochester nh hours

WebExit Flags. When an optimization solver completes its task, it sets an exit flag. An exit flag is an integer that is a code for the reason the solver halted its iterations. In general: … 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:
