I'm sharing a question a user asked me:

If you have a 1-D array of 1s and 0s (true and false), I know how to use Subset to get a list of the index items where the 1s occur. But what if I have a 2-D array (or more) or 1s and 0s -- is there a way for me to get a list of the coordinates where the 1s occur?

Here is my solution:

LocalIndex Ind := IndexesOf(A); MdArrayToTable(A)[.Col=Ind]

Two-D analog of Subset.ana

This is demonstrated in this model. There are other ways of doing it, and if you see another good way, feel free to add it to this thread.
