Hello.
I tried to calculate P. Please help me
function [Tc, P] = myfun2()
Ppv_rated = 250;
G = [5.75, 6, 6.365, 6.5, 6.185, 5.75, 5, 4.8, 5.5, 6.18, 6.15, 5.8];
Gref = 1000;
Kt = -0.485;
Tref = 25;
Tamb = [25.63, 26.7, 26.610, 25.46, 24.9, 24.01, 23.16, 23.01, 23.54, 23.78, 24.45, 25.3];
x = [0 2 5 7 8 9 10];
for i = 1:length(x)
for j = 1:length(Tamb)
Tc(j)= Tamb(j) + 0.0256*G(j);
P(i,j) = Ppv_rated*x(i)*(G(j)/Gref)*(1+Kt*(Tc(j)-Tref));
end
end
But Result is
The results is correct. BUT I want to calculate like this:
x1 = 0
P1 = Ppv_rated * x1 * (G1/Gref) * (1 + Kt * (Tc1 -Tref))
P2 = Ppv_rated * x1 * (G2/Gref) * (1 + Kt * (Tc2 -Tref))
...
...
P12 = Ppv_rated * x1 * (G12/Gref) * (1 + Kt * (Tc12 -Tref))
x2 = 2
P1 = Ppv_rated * x2 * (G1/Gref) * (1 + Kt * (Tc1 -Tref))
P2 = Ppv_rated * x2 * (G2/Gref) * (1 + Kt * (Tc2 -Tref))
...
...
P12 = Ppv_rated * x1 * (G12/Gref) * (1 + Kt * (Tc12 -Tref))
x7 = 10
P1 = Ppv_rated * x7 * (G1/Gref) * (1 + Kt * (Tc1 -Tref))
P2 = Ppv_rated * x7 * (G2/Gref) * (1 + Kt * (Tc2 -Tref))
...
...
P12 = Ppv_rated * x7 * (G12/Gref) * (1 + Kt * (Tc12 -Tref))
How do I do??? PLEASE HELP !!!

The problem with the approach suggested above is only the values of last iteration of x will be stored in P values. So, to keep the record of all iterations previously, refer to this code:
P(j,i) = Ppv_rated*x(i)*(G(j)/Gref)*(1+Kt*(Tc(j)-Tref));
