spliting a vector based on another vector

Dear all, I have two vectors, A and B. I want to split A into two vectors, C1 and C2, where C1 contains elements of A that are also in B and C2 contains elements of A that are NOT in B. Clearly, I can do C1 = intersect(A,B); C2 = setdiff(A,C1); but it looks cumbersome. Is there a one liner, something like [C1,C2] = f(A,B)? I'd much appreciate any and all help. Thanks so much! Best, John

Is there a one liner, something like [C1,C2] = f(A,B)?

There will be once you write such a function f(), which you can easily do!
