hi,

I have some clusters of users, I need to find intersections among the clusters. i.e is x=no. of users y=no. of users

what I need is x ∩ y=z

z is the no. of users in both clusters x and y

can I find a function do that?

many thanks in advance

Did you look at functions like intersect() and ismember()?
