Hi Hui,
Could you just shift your indexing such that you use i-1 and i instead? Its much more trivial to add a delay on a variable in simulink than read a future value.
n_iter = 5;
Z = [1 1 0 0 0];
T1 = ones(n_iter, 1).*300;
T2 = ones(n_iter, 1).*300;
S = 5;
W = 5;
for i = 2:(n_iter)
S = S * 10;
if Z(i) == 0
S = S * 2;
else
S = S;
end
W = W * 5;
if Z(i) == 0
W = W * 5.5;
else
W = W;
end
T1(i) = T1(i-1) + S;
T2(i) = T2(i-1) + W + T1(i);
end
