Think like a mathematician and solve an easier problem.
Consider a 1D array, [1 2 3] that you want to transform into another 1D array, [1 0 2 0 3]. Here is an easier problem -- transform the [1 2 3] array into [1 0 2 0 3 0] (a simple FOR loop where you replace a single element with a 2-element 1D array, [x 0], and use a concatenating output tunnel does the trick). Now just delete the last element!
Now that we have solved the 1D problem, extend it to a 2D problem. The inner loop creates a single row (of either 5 or 6 elements), and the outer loop assembles the rows into a 2D array by appending a row of zeros to each single row and outputting through a concatenating tunnel. You then trim the final (zero) row and possibly the final column if you didn't do in "inside the loop".
The other suggestion here will probably work (I didn't test it, but assume it wouldn't have been posted if it didn't work). However, just looking at it, I couldn't easily see what it was doing, so have to "take it on faith" that it works. My algorithm, particularly with a comment or two, should be "obviously correct" to someone who knows a little LabVIEW.
