            i made a dot indexed array called "pop" using repmat like the following
    pop.X = [];
    pop.V = [];
    pop.F = [];
    pop.pBestX = [];
    pop.pBestF = [];    
    pop = repmat(pop, N, 1)
and wanted to sort it by rows based on the columne "pop.F"
 what i mean is when pop.F(3) change position to pop.F(5) all other pop.X/pop.V in the same row will follow it
the pop array i have looks like this one

if there's a better way to make this kind of table and sort it, it would be greatly apreciated

        [~, index] = sort([pop.F]);
pop2       = pop(index);

				It's also worth mentioning that we can convert the struct array to a table using struct2table and sort the rows using sortrows.
s = [];
s(1).a = [1 2 3 4];
s(1).b = 2;
s(2).a = [5 6 7 8];
s(2).b = 1;
t = struct2table(s)
sortrows(t,"b")
