Until I stepped through your code, I did not notice it either, although, in hindsight it is obvious. The important thing is to use that idea, to step through code to see what is happening, and what went wrong.

Learn to execute your code ONE line at a time when you have a problem like this. Or learn to use the debugger. Then, READ THE ERROR MESSAGE.
I'll get you started. Here is where the problem occurs.
Gp = ((Kt*(1.015^(T-20)))*(P(i)/(P2+P(i)))*(TIC(i)/(C2+TIC(i)))*(N(i)/N2+N(i)))
Subscript indices must either be real positive integers or logicals.
Now, all you need to do is think about what that error means.
At that point, is i defined?
i
ans =
0 + 1i
Learning to debug your code is one of the most important skills in MATLAB. Time to start.
