i had a function with two variables f(x1,x2)

in loop for k times

how can i calculate the value of the function in each iteration??

C = cell(numel(x1));
for k = 1:numel(x1)
    C{k} = f(x1(k), x2(k)); % of f() is vectorised you won’t need a loop
end
celldisp(C)

thank you alot for your reply , but can you please explain what you meant by

C = cell(numel(x1)); ??

I was preallocating variable C , which makes the code more optimised . You could look up preallocation and explore why it’s important.
