XYZ coordinates to matrices?

[altenbach]

Are they adjacent positive integers starting with zero or random integers (-7000, 5, 1000000)?

It would be so much easier if you could show some typical data.

They are adjacent positive integers

[altenbach]

So, initialize a 2D array based on the max x and max y, then do my earlier suggestion, but wire x and y directly to the index inputs of "replace array subset".

I'm still rather unsure how to go about this.  Here is what I have come up with so far but it doesn't seem very close to working.  What might I do to modify it?

[altenbach · Accepted solution]

Here's what I would do....

 

Of course this assumes that all positions are unique, etc.

It works!  Thank you so much, you've really saved me a lot of time.

Make sure you fully understand why it works and how it works. Also be aware of the limitations.
