How can setup optimset for custom data types.

I'm putting xo as initial guess. I want custom data just restricted x0 subset [0,30], by create permutation.
x0 = [30 30 30 30 30 30 0 0 0 0 0 0 0 0 30 30 30 30 30 30];
[x, fval] = fminsearch(@objfun, x0);

I am sorry, but I do not understand what you are asking. Your image is from a ga example, but your question seems to be about fminsearch.
So can you please explain what you are trying to do, and what the problem is?

Rewrite the problem in terms of binary variables 0<=y(i)<=1 where y=x/30. Then use the IntCon argument and bound constraints to minimize in terms of y,
N=numberofVariables;
LB=zeros(1,N);
UB=ones(1,N);
IntCon=1:N;
fun=@(y) FitnessFcn(30*y);
x = 30*ga(fun,N,[],[],[],[],LB,UB,IntCon,options);

You should be wondering why Matlab thinks "options" is undefined, when the code you posted in your question defines it explicitly...
Regardless, Walter's solution will ultimately not work as written because (see My Remark) it tries to use IntCon and linear equalities simultaneously, which ga() does not allow.
