Hello, I want to return from array to single values.
This code's result is P calculated at each x values with matrix -----------> But I want to calculate P at each x value with single values. How do I do?
help me please!!
function [Tc, P] = myfunc()
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 ;
x = [0, 2, 5, 7, 8, 9, 10];
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 ];
Tc = Tamb + (0.0256 * G ) ;
P = ((Ppv_rated * x) .* ((G/Gref).*(1 + Kt*(Tc - Tref )))')';
disp(P)
end
This code result get matrix.

The size of x is different from G and Tamb

Yes sir. But I mean
for example:
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 * x2 * (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))
I want to calculate like this example. but I don't know how to write the code
So, each row of P in your code is for a value of x
P(1,:)
is the results for x=0
...
P(12,:)
is the rsults for x=10
The general row values is:
P(row,:)
row can be from 1 to 7
