MATLAB: Optimization of a unknown vector variable

Question

Hello ,

I have a code

a,b —–> variables should be vector(like a=[a1,a2,a3,a4])

x=h1*a^2+h2*b^2+h3;——>objctive fun(h1,h2,h3 are constants let say which has 1*4 value)

—->constraints are also present here.. so I am writting the code like

for i=1:4
x(i)=h1(i)*a^2+h2(i)*b^2+h3(i)
end
obj=sum(x);----->(objective function is basically summation of x )
x0=[1,1];
lb = [];
ub = [];
Aeq = [];
beq =[];
A = [];
b = [];
 fun=@(p) obj(p(1),p(2));
nonlcon =@constraintfcn;
opts = optimoptions('fmincon','Display','iter','Algorithm','sqp');
 [x_value,fval]  = fmincon(fun,x0,A,b,Aeq,beq,lb,ub,nonlcon,opts);

But I am not getting the ans,I want optimized value as vector .

Answer 1

H1=sum(h1);
H2=sum(h2);
H3=sum(h3);
obj=@(a,b) H1.*a.^2 +H2.*b.^2+H3;
x0=[1,1];
lb = [];
ub = [];
Aeq = [];
beq =[];
A = [];
b = [];
 fun=@(p) obj(p(1),p(2));
nonlcon =@constraintfcn;
opts = optimoptions('fmincon','Display','iter','Algorithm','sqp');
 [x_value,fval]  = fmincon( fun,x0,A,b,Aeq,beq,lb,ub,nonlcon,opts);
