I tried coding RK method but when I try to run that it is neither showing any plot nor any error.

@Gaurav Sharma: please show us how you are calling this function, with the exact values that you used. Note that the number of values plotted and returns depends on the input parameters, so what you are seeing depends entirely on those parameters (which you have not told us).
That code worked for me when I tried it:
>> [X,Y] = RK(3,2,1,4,5,6,3,7,8)
X =
7.0000 -17.4129 -83.1403
Y =
8.0000 13.8611 -61.8887

Except for the very first point, all your values are NaN, which don't plot. I didn't delve into the equations to figure out why, but you should do that. If you don't know how to debug, see this link http://blogs.mathworks.com/videos/2012/07/03/debugging-in-matlab/ because it's an essential skill you'll need in the future, so time spent learning it is well worth it.
