I used Matlab R2011a, when i try to implement Matlab example ( from R2016 Documentation)
http://www.mathworks.com/help/optim/ug/minimization-with-equality-constraints.html
I have problem when I try to execute the example and i get this messege
??? Undefined function or method 'optimoptions' for input arguments of type
'char'.
Error in ==> TestBrownfgh at 5
options =
optimoptions('fmincon','SpecifyObjectiveGradient',true,'HessianFcn','objective',...
which i suppose related to
options = optimoptions('fmincon','SpecifyObjectiveGradient',true,'HessianFcn','objective',...
'Algorithm','trust-region-reflective');
since i did not get any help in 2011a Demos related to SpecifyObjectiveGradient. Kindly can any one suggest how i can modify optimoptions to be suitable for this problem. Regards

That does not appear to be an option in R2011a. See the documentation< for the R2011a vesion of fmincon to determine if it can do what you want.
