     2     4
     2     2
     2     2
     3     1
     3     4
     2     4
     3     4
     4     3

Try this:

C =[...
     2     4
     2     4
     2     2
     2     2
     3     1
     3     4
     2     4
     3     4
     4     3]
 % Delete row if first element in a row
 % equals the second element. (Must be integers).
 rowsToDelete = C(:,1)==C(:,2)
 C(rowsToDelete,:) = []
