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: WebThese command-line simulation steps are best practices, even if you do not specify any other run-time options. Configure fmincon Options. By default, nonlinear MPC controllers optimize their control move using the fmincon function from the Optimization Toolbox. When you first create your controller, the Optimization.SolverOptions property of the …

At present, fmincon is defined as passing in the x information in the same shape as x0 was passed to it. A 'vectorized' flag would, I suspect, off more optimization possibilities for the objective function, whether on CPU or GPU.
