Question

I have two cell arrays, X and Y. Each cell array is made up of strings : i.e, X{i} is a string for all i, and so is Y{i}. I would like to find the intersection of the two cell arrays, (presumably a third cell array} that has the strings common to both X and Y.

Answer 1

There might a single function that does this – I don’t remember. But you can do it pretty easily with ismember:

a = {'a', 'b', 'c'};
b = {'b', 'd', 'a'};
intersection = a(ismember(a, b));
