What Is Optimization Toolbox?

2 TutorialThe arguments that the optimization function passes to outfun are• x — The point computed by the algorithm at the current iteration.• optimValues — Structure containing data from the current iteration.The example uses the following fields of optimValues:- optimValues.iteration — Number of the current iteration- optimValues.fval — Current objective function value- optimValues.searchdirection — Current search direction• state — The current state of the algorithmFor more information about these arguments, see “Output Function” on page6-16.Creating the M-File for the ExampleTo create the M-file for the example:1 Open a new M-file in the MATLAB editor.2 Copy and paste the following code into the M-file:function [history,searchdir] = runfmincon% Set up shared variables with OUTFUNhistory.x = [];history.fval = [];searchdir = [];% call optimizationx0 = [-1 1];options = optimset('outputfcn',@outfun,'display','iter',...'largescale','off');xsol = fmincon(@objfun,x0,[],[],[],[],[],[],@confun,options);function stop = outfun(x,optimValues,state)stop = false;2-90
