How to find the Union of two matrices with the same column size?

I have two matrices of different sizes: say A(n,2) and B(m,2). How to find the "Union" or "Intersection" of these two matrices?

*Hope the result will be: C(k,2)= A ⋃ B .....and D(p,2) =A ∩ B

**Thanks so much,

It looks like the union and intersect functions might come in handy here.

Try

C = union(A, B, 'rows');
D = intersect(A, B, 'rows');
