MATLAB优化工具箱如何得到每次迭代的目标函数值

1、创建output function%%% 代码%state.Generation 当前代墙绅褡孛数%state.Score 种群的目标函数值function [state, options,optchanged] = outfun(options,state,flag)optchanged = false;switch flagcase 'init' disp('Starting the algorithm'); case {'iter','interrupt'} plot(state.Generation,min(state.Score(:,1)),'.'); hold on; disp('Iterating ...'); disp(state.Generation); case 'done' disp('Performing final task');end%%%

2、创建options在optimset中加入'OutputFcn', @outfun%%%options = optimset('OutputFcn', @outfun);%%%

3、运行程序[x,fval,flag,output,population] = gamultiobj(@objfun,nvars,... [],[]荑樊综鲶,[],[],lb,ub,options);
