Indexing a vector in a particular fashion

I have a vector: [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]

I want to index this vector in the following order: [9, 10, 7, 8, 5, 6, 3, 4, 1, 2]

How to do that?

Index it pretty much exactly as ot was written —

v = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10];
idx = [9, 10, 7, 8, 5, 6, 3, 4, 1, 2];
out = v(idx)

out = 1×10

9 10 7 8 5 6 3 4 1 2
