Array 2D

[Mark87]

Hi I have a 2D array (in the VI this is an example of 2D array). I want that for each column I read the first element of each columns and to subtract the first elements to all the elements of the relative column. For example I read the first element of the first column and I subtract its to all the other elements of the first column, then I read the first element of the second column and I subtract its to all the elements of the second column. This is a prove VI that I have created but I have no idea on how to obtain the new 2D array with all the new columns that I create with the subtraction of the first elements.

I hope I have understood your problem, try this solution.

Let me know.

Dear Ayanez, thanks for your reply. Can you give me an image or a VI with 2011 version. I don't have the last version of LabVIEW and so I can't see your VI. Sorry!

Try something like this.

Of course there are always several ways to do something. Here's a slight variation that might be even simpler.
