flatten

Format: flatten( a )

Arguments: [any] a Hierarchical list or matrix

Returns: [any] Input list flattened to one level

Description: In DScript you can specify lists that contain sublists as elements. This is the way you specify a 2-dimensional matrix, for example. The flatten primitive combines all sublists to create a single, flat list. If the list already contains only one dimension, it is not altered.

Examples: flatten([[1,2],[3,4]]) = [1,2,3,4]

flatten([1,2,3,4]) = [1,2,3,4]
