A small question about the OutputFcn function in the optimization tool~~Thank you!

http://www.mathworks.com/help/techdoc/math/bsgpq6p-23.html

in this page there is a example to answer my former question I posted yestoday. you can see it in the Example of a Nested Output Function headline~~

with this example changed something,just like this(for I don't need the history variable):

function [x fval] = myproblem1(x0)

      options = optimset('OutputFcn', @myoutput,'Display','iter');

      [x fval] = fminsearch(@objfun, x0,options);

      function stop = myoutput(x,~,state)
          stop = false;
          if state == 'iter'
          disp(['                                                   x = ',num2str(x)]);

          end

      end

      function z = objfun(x)

        z = exp(x(1))*(4*x(1)^2+2*x(2)^2+x(1)*x(2)+2*x(2));
      end
  end

and then I input the commmand:

[  x fval] = myproblem1([-1 1])

it did give a right result.

but if you input：

 objfun(x)

it comes out like this:

> objfun(x) 
ans = 
0.3344

I don't understand,doesn't the return value of the fminsearch function equal to the minimum value of objfun(x)?So,why doesn't the ans above equal to -0.5689,as written in the help page you mentioned?

Thank you!!!!
