Elements in a set that are not elements of another set (relative complement)

Question

In matlab, how can I implement the following?

Say that I have some set A and another set B, both of which have some elements. How can I write a function that returns only the values of B that are not in A (relative complement of A in B B\A?

Thanks.

Thanks for your answer. Since I need the elements in `B` that are not in `A`, I should write `setdiff(B,A)`, right? – Simplicity Feb 08 '13 at 10:40
@Med-SWEng it appears as if you are right. – Shai Feb 08 '13 at 12:13
