Hi, I will like to ask for the objective function is there any other way to write instead of typing all the variables (X11 to X14) into the function. - f([X11 X12 X13 X14])

variables = {'X11','X12','X13','X14'};
N = length(variables);
display (N);
% create variables for indexing 
for v = 1:N  
   eval([variables{v},' = ', num2str(v),';']); 
end
% objective function
f = zeros(size(variables));
f([X11 X12 X13 X14 ])=[0.08,0.12,0.16,0.20];

Thanks

I am at a loss as to what your intended result is. If X11 X12 X13 X14 are not positive integers, then f([X11 X12 X13 X14 ])=[0.08,0.12,0.16,0.20] would be trying to index the array f at non-integer locations.

I do not see where "objective function" comes into this?
