For example: I have the following array of data.
column 1 column 2
1 2
2 3
3 4
4 5
5 6
6 7
7 8
8 9
I would like to make a new array of data sets with
column 1 column 2
2 3

One approach: 
A = [1                           2
     2                           3 
     3                           4
     4                           5
     5                           6
     6                           7
     7                           8 
     8                           9];
L = ismember(A(:,1), [2 4 5 8]);
B = A(L,:)
produces: 
B =
     2     3
     4     5
     5     6
     8     9
