intersection

intersection(X, Y) or X&Y

X and Y can be sets, or integer scalars/vectors of the same length.

If both X and Y are sets, return the intersection of the two sets.

If X and Y are integer scalars/vectors, conduct the bitwise operation "AND".

x=set([5,5,3,4,6])
y=set(8 9 4 4 6)
x & y;
// output
set(4,6)

6 7 8 & 4 5 6;
// output
[4,5,0]
