Real coded NSGA II

I have to do multi-objective optimization using real coded NSGA II for a problem with two objectives. I have 19 stations from which 10 stations are to be selected based on x(1) and x(2) values. x(1) is to be maximized and x(2) is to be minimized. x(1) and x(2) values for each station are known. x(1) values for 19 stations are 2.46, 3.10, 2.57, 2.79, 2.91, 2.29, 2.60, 3.35, 3.29, 3.01, 3.21, 3.20, 2.92, 3.87, 3.57, 2.88, 2.97, 2.75 and 3.03 respectively (2.46 for station 1 and 3.03 for station 19). x(2) values for 19 stations are 0.62, 1.03, 0.57, 0.65, 0.60, 0.53, 0.58, 1.48, 1.46, 1.25, 1.43, 1.42, 1.19, 1.47, 1.45, 1.02, 1.06, 0.91 and 1.08 respectively (0.62 for station 1 and 1.08 for station 19). Can you please modify the NSGA II code (which I downloaded from matlab central) posted here for my purpose?
