Hi I have two data matrix, one is A and the other is B. I want to compare each column in A to B and if a match is found in B, then the whole column(s) in B should be extracted. In the attached file, under A, 11, 12, 13 and 14 can also be found in B. In this case all the values under 11, 12, 13 and 14 in B are extracted into C.
I tried using intersect but it doens't work.
Thanks!

If I understand correctly, then
C = B(:,ismember(B(1,:),A))
does what you want.
From your example, it looks like A is a row vector, and you want to compare it to the first row of B. That's what this code does.
