how to extract one dimension out of a two dimensional array

Go to solution


May be this question is too naive and simple.I have a two dimensional array (two columns and 256 rows). All I want is to extract one of these columns as a separate one dimensional array. It seems like a very very basic task that any programming language should address. However, I could not find the right funciton in the array functions list. I am sure I am missing something very obvious. I tried index array, array subset, array to cluster and reshape array. None of them is the right function for this purpose. I have used LabVIEW for a quite a while now, but still I can not find a solution to this basic problem. Can someone help me out.

Hi -


With the Index Array  function have you tried wiring a number to the input labeled index (col)?


See the attached vi for an example.

Yes. That is exactly what I wanted to do. Thank you. I could not open your VI because I have LabVIEW 7. However, I understood from your explanations. I was getting confused by the word "disabled" in "disabled index (col)". After setting that to 1 (meaning my second column) I coudl extract the second column. Thank you for the help.

Hi Jahan,


next time you should mark the correct message as solution - and not your own reply...

Sorry about that. I tried correcting it but didn't work. I will keep that in mind for the future.
