How do I multiply specific numbers in two different matrices by each other?

So for instance, If I had:

A=[1 2 3]

B=[4 5 6]

How would I compute 3*5 to get 15? (I'd like to know how to do this for any operator not just multiplication)

Just use indexing, as like any other programming language, for example

output = A(3) * B(2)

Replace * with / or + or whatever operator you want.
