Owning Palette: Array Functions

Requires: Base Development System

Divides the elements of array into the output arrays, placing elements into the outputs successively. This function drops any elements that cause the output arrays to have different lengths.

You also can add additional output terminals by resizing the function.

array can be a 1D array of any type.
elements 0, n, 2n, ... is the first output array. The function stores array[0] at index 0 of the first output array, array[1] is stored at index 0 of the second output array, array[n-1] at index 0 of the last output array, array[n] at index 1 of the first output array, and so on, where n is the number of output terminals for this function.

For example, assume the array has 16 elements and that you wire four output arrays. The first output array receives elements 0, 4, 8, and 12. The second output array receives elements 1, 5, 9, and 13. The third output array receives elements 2, 6, 10, and 14. The last output array receives elements 3, 7, 11, and 15. This is the expected behavior.

If you remove one element from the input array there will only be 15 elements. The last decimated array will only have 3 elements (3, 7, and 11) since element 15 was deleted. Since the function will only return arrays of the same size, the other 3 decimated arrays will drop their last element so that all of the arrays now contain 3 elements.
elements 1, n+1, 2n+1, … is the second output array, and so on.
