[C,ia,ib] = intersect(A,B)

For example:

>> A = [1,2,3,4,5,6,7];
>> B = [2,3,4,8,9,0,7];
>> [C,ia,ib] = intersect(A,B)
C =
   2   3   4   7
ia =
   2   3   4   7
ib =
   1   2   3   7

[div]

Thank you for your replay sir but i want A=[1,2,3,4,5,1,9] B=[1,4,3,7,5,1,9] so answer should be 1,3,5,1,9 .....i want those element which are common in same position in A and B with their index . And intersect give common elements with no repetition. Please help me out sir

@div: well, that is a different question. Try this:

>> A = [1,2,3,4,5,1,9];
>> B = [1,4,3,7,5,1,9];
>> C = A(A==B)
C =
   1   3   5   1   9
>> X = find(A==B) % (but logical indices are usually more efficient)
X =
   1   3   5   6   7

not working sir . Please help this out.

It DOES work. I just copied and pasted and it worked fine. Post the code that you subsequently altered so we can see how your alterations ruined it.
