How to sort a dot indexed array by rows based on one column

1 view (last 30 days)
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);

i was thinking it could be done within the same table but that works perfectly.
thank you,

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)
t = 2×2 table
a b ________________ _ 1 2 3 4 2 5 6 7 8 1
sortrows(t,"b")
ans = 2×2 table
a b ________________ _ 5 6 7 8 1 1 2 3 4 2
