How to Average an Array based on another Array?

[LeonelDeLaCruz]

Example:

I have ARRAY1 with the following:

1

1

1

2

2

3

ARRAY2 Contains:

1

2

3

4

5

6

In the end ARRAY3 would contain:

2                  (1+2+3)/3

4.5               (4+5)/2

6                  (6)/1

Here is my first go at it.  There are plenty of improvements that can be made (conditional index is one) but it appears to do what you want.  Array 1 and 2 must be the same size for it to work.

Thanks... This will get me started.
