This allows fminunc to use the gradient when minimizing the function. 'MaxIter', 400: set fminunc run for at most 400 steps before it terminates.

WebSpeci cally, we set the GradObj option to on, which tells fminunc that our function returns both the cost and the gradient. This allows fminunc to use the gradient when minimizing the function. Furthermore, we set the MaxIter option to 400, so that fminunc will run for at most 400 steps before it terminates. WebThe main difference in creating options is: For optimoptions, you include the solver name as the first argument. options = optimoptions ( SolverName ,Name,Value,...) For optimset, the syntax does not include the solver name. options = optimset (Name,Value, ...) In both cases, you can query or change options by using dot notation.

Weboptions = optimset(optimfun) creates an options structure optionswith all parameter names and default values relevant to the optimization function optimfun. options = optimset(oldopts,'param1',value1,...) creates a copy of oldopts, modifying the specified parameters with the specified values. options = optimset(oldopts,newopts) Web: options = optimset (old, new) Create options structure for optimization functions.
