Stopping intlinprog if fval isn't changing

Dear All
I'm quite new to Matlab and I'm using it for optimizations. Now I'm trying to define some stopping criteria but I don't get it. How can i stop a intlinprog function if my fval value isn't changing over a certain amount of nodes? Is that even possible?
This is my code so far:
clear all
A = xlsread('Daten_jpd.xlsm','A');
Aeq = xlsread('Daten_jpd.xlsm','Aeq');
beq = xlsread('Daten_jpd.xlsm','beq');
b = xlsread('Daten_jpd.xlsm','b');
lb=xlsread('Daten_jpd.xlsm','lb');
ub=xlsread('Daten_jpd.xlsm','ub');
c=xlsread('Daten_jpd.xlsm','c');
intcon=xlsread('Daten_jpd.xlsm','intcon');
[x,valuef]=intlinprog(c,intcon,A,b,Aeq,beq,lb,ub);
I tried to use
options = optimoptions(@intlinprog,'OutputFcn',@stopFcn);
to include a stop Function, but there i got an error:
Error using optimoptions (line 105)
'OutputFcn' is not an option for INTLINPROG.
A list of options can be found on the INTLINPROG documentation page.
Thanks a lot for your Help!
Cheers yvlu

You probably have MATLAB R2014a, which does not have output function support for intlinprog. See the release notes.
