For loop question help

I have two vectors. A = [ 1 2 3 4 6] and x = [5 3 2 1]. For every value in x, I want to return the corresponding index value in A. For example, the first value of x is 5, so I want the loop to return A(5) =6. How could I do this?

You don't need a loop.

output = A(x);

gives you all the values at once. (Then you can loop over that if you need to)
