Error with nested function to output history x values of FMINCON

Hello, I want to retrieve the values of x at each iteration of an optimization routine using FMINCON. I've defined a nested function to save in history variable the x values. But, when I run the code, It says that I don't have enough inputs in line 4, which is where I call the fmincon. This is the nested function:

 function OptimalResult = iteroutfun(x0,t,e)
    history = [];
    options=optimset('Display','iter', 'FunValCheck','on', 'OutputFcn', @myoutput);
    OptimalResult = fmincon(@(x) ObjFunction3a(x,t,e), x0, [], [], [], [], [], [], @(x)ConstraintsOR3a(x,e,t), options);

    function stop = myoutput(x,optimvalues,state);
        stop = false;
        if isequal(state, 'iter')
            history = [history; x];
        end
    end
end

If someone has any idea of what is that I'm missing I'll appreciate it very much,

Thank you, Martha

You do not show ObjFunction3a

Thank you Walter, I added the ObjFunction3a and the ConstraintsOR3a to the nested function and it worked well.
