Hi oi,

do you actually have a matrix or just a simple 2D array? That is quite a difference in LabVIEW, please use exactly the label that is shown in the context help! (Or show a picture or even better a VI!)

Use either IndexArray, GetSubmatrix - or simple autoindexing of a FOR loop!

i have matrix 51*4 and want to get each coloums as 1-D array??

Hi oi,

I already proposed several solutions. Have you tried any of them?

As mentioned, Index array allows you to get rows or colums of a 2D array if you leave one index disconnected.

To get columns, you need to wire the lower index of the two. Here's example code to get the first four columns of a 2D array.

How different are the arithmetic operations you want to apply? Can you show us a typical example? There are probably ways to do it all at once.
