i need a function that returns the indexes of the top n highest values
in a vector.

example:

a=[1 2 3 2 3 5 7 8 9 21 55 23 12 78 15]

b=top(a,5)

b=[14 11 12 10 15]

the order of b does not matter

one of the solutions

a=[1 2 3 2 3 5 7 8 9 21 55 23 12 78 15];
[as,ax]=sort(a,'descend');
r=ax(1:5)
