decimate a 2d array

[Beaton]

I was wondering how I would decimate a 2d array into 3D with 24 pages

That's not really a decimation....

Have a look at "reshape array" in the array palette. It might just do what you need. 🙂

Of course there are infinite possibilities to slice&dice a 2D array so the exact procedure will depend on how things are arranged. Another possibility would be to use "array subset" in a loop, autoindexing to 3D at the right loop boundary.

Sorry about the first post, let me explain myself better.

I want to do as shown in the attached picture but from a 2D to 3D.

Reshape almost works except that what I want to do is have the first row and every 24th one after it be in the first page, and so on for the other 23 pages.

Well, there is probably a smarter way, but I would just Do the autoindexing, e.g. as follows:

You might still need to tweak it a bit.
