I want to minimize a function with a constraint which has 8 inputs. The problem is I cannot call the by x(1), x(2),etc because they are generated in another program in each loop and thos variables are used in other places. Does anyone have suggestion?

Please show your code attempt, and show how the functions are being generated.

this is my constraint:
function NLPS = LPS(Nwt, Nbat, Npv, tilt, TArray, KtArray, LArray, WindArray)
EBatMax = 6.936*2*Nbat;
EBatMin = 0.5*EBatMax;
Ebat = EBatMax;
NLPS = 0;
for i=1:8760
T = TArray(i);
Kt = KtArray(i);
L = LArray(i);
Wind = WindArray(i);
[B0, delta, w0, ws] = daily_beam(i,tilt);
Epv = out_PV(Kt, Npv, T, B0, tilt, delta, w0, ws);
Ewt = out_wt(Wind, Nwt);
Generate = Epv + Ewt;
[EBatNew, Gbat] = out_bat(Ebat, EBatMin, EBatMax, Generate, L);
Ebat = EBatNew;
Generate = Generate + Gbat;
Net = L - Generate*0.9;
if Net < 0
NLPS = NLPS + 1;
end
end
end
this is the function to be minimized:
C=cost(Nbat,Nwt,Npv)
the inputs of NLPS are generated in other functions. genetic is supposed to generate some numbers for Nbat,Npv,Nbat and tilt in a way that minimizes the cost and also satisfies the constraint function.

Something like,
constraint_function = @(x) LPS(x(1), x(2), x(3), tilt, TArray, KtArray, LArray, WindArray);
??

yes exactly. I tried and I get 'too many input arguments". Do you have any idea what is wrong here?

I tried to simplify the issue optimizing this function `function z=f(x) f=(x(1)-2)^2+(x(2)-1)^2`. I input this in command window: [x fval]=ga(@f,2). But still I get same error!
