@ RAJAN PRASAD: your question is not clear: do you want to sort the data (as your title states), or do you want to calculate differences between values (as your examples shows) ?

This code locates the beginning and end values of any non-zero sequence, and calculates their differences:
>> X = [0,0,3,4,5,0,0,0,0,10,11,12,13,14,15,0,0,0,0,20,21,22,0,0,0];
>> Y = diff([0,X,0]>0);
>> X(Y(2:end)<0) - X(Y(1:end-1)>0)
ans =
2 5 2
Have a look at X(Y(2:end)<0) and X(Y(1:end-1)>0) if you want to know how this works.
