Would you elaborate what is your code inside of "for loop"? In the captured image's code, I cannot see the index "i" is using inside for loop like the following mpcmove function example.
t = 0:ts:40;
N = length(t);
y = zeros(N,1);
u = zeros(N,1);
for i = 1:N
y(i) = 0.25*xc.Plant;
u(i) = mpcmove(mpcobj,xc,y(i),r);
end
