I want to create an objective function that will be the sum of a series of 100 variables that will have a range of values between 0 and 1.
Instead writing down a sum like this:
x(1)+x(2)+ ... + x(100)
I want to find an automated way for this sum of x()s to be created.

function [lb,ub,dim,fobj] = Get_Functions_details(F)
switch F
case 'F1'
fobj = @F1;
lb=0;
ub=1;
dim=100;
end
end
function o = F1(x)
o=sum(x.^2);
end

Hi @GEORGIOS BEKAS,
You can create a symbolic vector x and then compute the sum of all elements in x.
numVariables = 100;
% Create a vector of symbolic variables
x = sym('x', [1 numVariables]);
% Define the objective function as the sum of the variables
objectiveFunction = sum(x);
% Display the objective function
disp(objectiveFunction);
This way, you have an objective function that will be the sum of a series of 100 variables.
