I have an 10 rows & 4 columns array , i multiply each element by 2 , then put each result in a new array, but I get an 1 row & 40 columns array. To make it clear, i attached my Program (with some explanation in it).
I can't open your vi (LV7.0) so I attach you a simple example that may answer your question.
Hope this helps.

I know this probably isn't the best way, but it works.
Using the indexing feature (a really powerful feature of LabVIEW - right click on loop tunnel->enable indexing) means you can wire an array directly to a loop border, instead of having to get the size and wire it to N... Hope this helps!
And Geoff , thanks a lot, your solution solved my problem 🙂 But if you don't mind ,i would like to know why in your for-loop , u didn't specifed the number of iteration ? Ussualy one should define the number of iteration, so the for-loop can work (from my Labview Handbook). It must be a new programming technique for me.
Could you post your vi as LV7.0 (Save with options...)

It was what I was mentioning in my last message about indexing.
Notice how on the side of the loop border the tunnel (connection between array and loop) looks different? If you enable indexing on a loop, the loop automatically assigns the number of iterations to be the number of elements in the array. Hopefully this image makes things more clear...
You can do this by right clicking on the loop tunnel.. notice how the bottom tunnel has enable indexing available? If I were to right click on the top tunnel, it would say disable indexing.
Have a look at my vi or the picture ulf attached. This solution has several advantages in comparison to the one you want to use:
1. It needs less memory, because you do not have two for-loops 2. It's easier to understand 3. It's faster
So I suggest you to use our version.
