I'm gonna try to explain you what to do even if my english is bad. Create a for loop in which you can auto-index your array. In the for loop the only VI you have to include is buid array (make 3 inputs). Then create a shift register on your loop. The first input of build array has to be connected to this register. The second and third inputs have to be connected to your auto-indexed array. Wire the output of the buid array VI to the output of the shift register. Don't forget to create an empty array to initialize your shift register.
Hope this helps Jumarion
