# how do I calculate all values in for loop?

I want to calculate in each x = [0, 2, 5, 7, 8, 9, 10 ] -----> Output P equation.
I tried to write in below code. BUT when its only x = 10, result calculated. I want to calculate all x values.
How do I do?
m-file
function [Tc, P] = myfun1(Ppv_rated, x, G , Gref, Kt, Tref, Tamb)
for x = [0,2,5,7,8,9,10]
Tc = Tamb + (0.0256 * G);
P = (Ppv_rated * x) .* (G/Gref).*(1 + Kt*(Tc - Tref));
end
end
COMMAND WINDOW
>> 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];
>> [Tc, P] = myfun1(Ppv_rated, x, G , Gref, Kt, Tref, Tamb)
RESULT

You need to save each value in aloop.
function [Tc, P] = myfun1(Ppv_rated, x, G , Gref, Kt, Tref, Tamb)
m = numel(x);
n = numel(Tamb) ;
Tc = zeros(m,n) ;
P = zeros(m,n) ;
for i = 1:length(x)
Tc(i,:) = Tamb + (0.0256 * G) ;
P(i,:) = (Ppv_rated * x(i)) .* (G/Gref).*(1 + Kt*(Tc(i,:) - Tref));
end
end
You need not to use a loop and you can use all vector operations.
function [Tc, P] = myfun1(Ppv_rated, x, G , Gref, Kt, Tref, Tamb)
Tc = Tamb + (0.0256 * G) ;
PP = ((Ppv_rated * x) .* ((G/Gref).*(1 + Kt*(Tc - Tref)))')';
end

another m-file using PSO code worked. But I don't know why myfunc m-file doesn't work.

%if true
% code
% end
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

Thank you sir.
I understood. Its working. I have a question.
I want to input Ppv_rated, G, Gref, Kt, Tref, Tamb in this function not command window. Is it possible?
