Replacing a nested for-loop

Hey everyone!
I am doing pairwise comparisons of strings in a cell array using a function that I wrote. Right now I have it in a nested for-loop that looks like this
D = {'string1','string2','stringn'}
for k = 1:numel(D)
for j = k:numel(D)
M(k,j) = myfunction(D{k},D{j});
end
end
This runs fairly slow. My question is there a faster way to do these pairwise comparisons using something like arrayfun?

No. arrayfun() uses a for loop internally, so it is no faster.
You should consider vectorizing "myfunction".
