One can check whether the index number is odd or even with
if mod(i,2)==1
% do something

oh yes, I am sorry I deleted that comment. It was:
wouldn't this require more manual work?

Without any loop, this should work:

If you are going to select 1 number, or 3 numbers, or 5 numbers, or however many numbers you want, you can specify their indexes but you need to decide which one(s). For example, if you are going to select (extract) 3 numbers, which three are they? The first three? The last three? The numbers at indexes 4, 6, and 10? You need some kind of rule.
Or do you want every possible combination of 3 numbers?
For example, let's say you wanted the 3 numbers at indexes 2, 8, and 11, from vector v, you'd do
v3 = v([2,8,11])
