Given
A = [1 2 3 6 7 9 10];
B = [4 7 8 10];
How would I determine that 7 and 10 are common to both vectors?
find(ismember(A,B))
appears to return the index of A that has the number(s) shared with B, which is not quite what I want. I want to return the values 7 and 10. How do I do that? I have very large vectors, but here I'm giving a simple example.

Use
v = intersect(A,B)
