Interpolating between array elements

On the XSI mailing list last week, there was a question about “resizing an array using interpolation”.
The goal was to resize an array by interpolating between the elements of the original array.
For example, given this array:

[0, 5, 10]

how to you get this array ?

[0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10]

Alan Fregtman suggested bezier interpolation with the Fit Bezier Curve compound. I gave it a try, and here’s a screenshot. I added a branch to go back to a scalar array from the vector array.
