How can I pass extra parameters to an output function in the Optimization Toolbox?

I'm trying to specify an output function in my optimization options as an anonymous function so as to pass additional parameters to it. My options structure is defined as follows:
options = optimset('outputfcn',@(x)outfun(x,extraArg),'display','iter',...
'Algorithm','active-set');
...
function stop = outfun(x,optimValues,state,extraarg)
...
...
end % nested function
As a result, I get the following error:
??? Error using ==> runfminsearch>@(x)myfunObj(x,k1,k2,k3)
Too many input arguments.
I need to pass additional arguments to an output function using an anonymous function.

An output function expects 3 input arguments:
stop = outfun(x, optimValues, state)
Thus, the anonymous function, which is the value of the 'OutputFcn' property in the call to OPTIMSET, should be defined as follows:
options = optimset('outputfcn',@(x,optimValues,state)outfun(x,optimValues,state,extraArg),'display','iter',...
'Algorithm','active-set');
That is, @(x,optimValues,state)outfun(x,optimValues,state,extraArg) instead of @(x)outfun(x,extraArg).
