在 MATLAB Online 中打开

   function GUI
     uicontrol('Style', 'pushbutton', 'Units', 'norm', 'Position', [.1 .9 .05 .09], 'Callback', @anneal_it);
   end
   function anneal_it(src, evt)
     X0 = rand(1,2);
     [x, fval] = sa(@function_to_anneal, X0);
     fprintf('Minimum value %g at location (%g, %g)', fval, x(1), x(2));
   end
   function y = function_to_anneal(X)
     y = (4 - 2.1*x(1)^2 + x(1)^4/3)*x(1)^2 + x(1)*x(2) + ...
       (-4 + 4*x(2)^2)*x(2)^2;
   end
