Hello
I have cell array data example. D = {[1 2 5];[1 2 4 6];[2 4 5 6];[2 5];[1 4 6]}
the answer is 3
I want to know how to calculate a frequency of [2 5] which occurs in D by not using loop.
thank you

[2 5] must be the only element? 2 and 5 must be adjacent? In that order or order is irrelevant?
Some of these possibilities I don't think can be done without at least an implicit loop using one of the *fun() functions.

Can so?
out = sum(cellfun(@(x)all(ismember([2 5],x)),D));

I think this may be close to what you are looking for.
freqElements = sum(cellfun(@(x) mean(ismember([2 5],x)) == 1,D));
