Intersection of two 7x2 matrix

Hi, i have a matrix Y =
1 7
2 6
3 5
4 4
5 3
6 2
7 1
and v =
1 2
4 6
3 5
7 1
9 8
2 4
8 1
How can I get the matrix Ynv? The find and intersect command doesn't seem to work for a matrix. I've tried the following:
for j=1:size(Y,1)
for i = 1:size(Y,1)
if Y(i,:)==v(j,:)
ind(k)=i;
k=k+1; %with k=1;
end
end
end
but I don't want to use the for loop. Thanks

Ynv = intersect(Y,v,'rows')

[c,iY,iV] = intersect(Y,v,'rows');
gives you the rows of the matrix that intersect in c. Otherwise, what do you mean get the intersection of the two matrices, you mean any element common to both?

Thanks. I wanted the pair of elements of Y that is in v. It works great. Thanks again
