how can I use for loop to change non linear constraints?

I need to optimize the same function but with different element of the same non linear constraits function(NONLINCON). can I use a for loop to fill the nonlincon and then optimize the objective function? For example:
e=@(x)....
[c,ceq]=nlcon(x,t,p) % function.m
for i=1:p
t=tmax(i,1); %vector
p=pxy(i,2); %vector
constx=nlcon(x,t,p);
[x,fval]=fmincon(e,x0,A,b,Aeq,beq,lb,ub,constx)
end
Can it works?

Hi Francesco,
I understand that you have a non linear contraint function to be optimized multiple times in for loop which depends on additional parameters .
You can use 'evalin' to access the variable in the base workspace in your nonlinear constraint function.
Here is the documentation for evalin
Hope this helps you.
