Conversion to double from function_handle is not possible.

I'm trying to solve an economic dispatch problem using the fmincon function, but i'm getting many different errors in the function inside the loop. Can you please help me run this code without errors? This is my first time using fmincon.
Nc = 3;
a = [ 0.06 0.03 0.04];
b = [ 0.5 0.25 0.3];
c = [ 5 4 2 ];
p0 = [2 4 7 ];
objective = zeros(1,3);
for i = 1:Nc
objective(i) = @(p) a(i)^2 * p(i)^2 + b(i) * p(i) + c(i);
end
pd = 550;
A = [];
b = [];
Aeq = [ p(1) p(2) p(3)];
beq = [ pd ];
lb = [ 0 0 0 ];
ub = [ 4 6 9 ];
% disp([' Initial Objectives: ' num2str(objective(p0))])
cc = fmincon(objective(i), p0, A , b , Aeq, beq, lb, ub);
disp(cc)

objective = zeros(1,3); % Here objective is a double
for i = 1:Nc
% And here you want to store a function handle in the double elements:
objective(i) = @(p) a(i)^2 * p(i)^2 + b(i) * p(i) + c(i);
end
This cannot work.
Try this instead:
objective = @(p) a.^2 .* p.^2 + b .* p + c;
