I want to find two elements in A are also in B,and I would like to know B's index.
So the answer is 1 2 4 5 in B.
A=[1,3,7]
B=[1 8 3;
1 2 3;
3 4 5;
1 7 9
2 1 3];
This is what I tried.But clearly,it's not smart
find(B(:,1)==A(1,1)&B(:,2)==A(1,2))
find(B(:,1)==A(1,1)&B(:,3)==A(1,2))
find(B(:,2)==A(1,1)&B(:,3)==A(1,2))
(I can sort them and use ismember but it's still not intuitive. Any other function?)
