How to delete columns from a array
Solved!
You can look at it from two different angles:
- You can delete the extra columns
- you can keep only the fist three columns
Easiest would be to use "array subset" and select the first three columns. See picture.
(This assumes that you want the three columns as a 2D array. If you want them as three 1D arrays, you would use "index array" resized to three outputs.)
Thank you, this seems to be the way of doing it. May I just ask how i can define the columns instead of the rows?

Please define what you mean by "extracting data from columns". This can be interpreted in many different ways (The above solutions extraced the first three columns, possibly not quite the same).
You could for example transpose the array and autoindex at a FOR loop with a "3" wired to N and it will process the first three columns, one per iteration.
Please clarify what you need to do, exactly. 😉

Look at my picture above. Wire the number of columns to the lowest "size" input and leave the rest of the lower inputs of "array subset" unwired.

It depends where you are giving the length value. 1st index and length corresponds to row and the 2nd index and length corresponds to coloumn.
Good luck
