I have two vectors of pixels with their position x and y length of vectors is not the same and their length is 520 There is an exemple: A = 20 40 60 120 30 50 100 140 B = 40 20 50 30 the result : pixels (20,30) and (40,50) are the same in two vectors so i have D = 40 20 as a result 50 30

To clarify, are you trying to locate points in B that are also in A?

@Mohamed: Do you see the difference in the readability of Sebastian's example code and your one? It would be very helpful, when you edit the original question and insert full stops at the end of each sentence. To learn more about code formatting and asking good questions, follow the "About MATLAB Answers" link on the left side.

doc intersect
And specifically:
intersect(A,B);
or ismember
C = A(ismember(A,B))

Seems like it, based on his comment. But why are these "neighbors" of some pixels? Does this do what his subject line asks?

They were selected based on their responses to a survey?
