How do I plot the output of fmincon when I'm already using options twice; once to include gradient using optimoptions and the next to plot using optiset?

So as said in the question, I have to define options twice but I can't use them concurrently. How can I prevent conflict between include gradient and the output function? Note, that I'm using Matlab 2015 and that one of the options is commented out. Thanks!
resdof=[1,2,12];
dof=[1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22];
freedof=setdiff(dof,resdof);
ndof=[1,7,7,8,2,7,1,2,2,8,2,3,8,9,3,8,3,4,3,9,9,10,4,9,4,5,4,10,10,11,5,10,5,6,5,11,6,11];
ndof=[1,7,7,8,2,7,1,2,2,8,2,3,8,9,3,8,3,4,3,9,9,10,4,9,4,5,4,10,10,11,5,10,5,6,5,11,6,11];
Lvec=zeros(1,22);
Lvec(1,6)=1;
dfdu=Lvec(freedof);
x0=0.0005*ones(1,19);
lb=zeros(1,19);
options =optimoptions('fmincon','GradObj','on');
%options=optimset('OutputFcn',@outfun);
[x,fval,optimValues.iteration,iterations]=fmincon(@objfun,x0,[],[],[],[],lb,[],@nlcon,options)

Feel free to try
options = optimoptions('fmincon','GradObj','on','OutputFcn',@outfun);
Or, for people who like to set only one option at a time,
options = optimoptions('fmincon','GradObj','on');
options = optimoptions(options,'OutputFcn',@outfun);
