Auto index by row or column

[juergen]

Hi all

What I need is the possibility to auto index a 2 dim array by column or by row

With a right click at the tunnel to have this two options

This is a duplicate of Allow user to select dimension when array indexing in For/While loop which really needs to get more kudoes.

(And also Auto-indexing Tunnels and Multi-Dimensional Arrays).

Until this idea is selected and implemented, the easy solution is to transpose the 2-D array before sending it into the loop for auto-indexing.

Adding a "transpose" before the tunnel is actually very cheap, because it only changes a flag and does not actually touch the array in memory. It is not a big deal.

For a complete idea, you would also need the same functionality at the output tunnels.

Or this idea...

Hi altenbach

When I use the transpose function the "show buffer allocation tool" show me that LabVIEW is using a new buffer

It might need to make a new copy for various reasons (e.g. branching), but it might just flag it as "transposed" instead of shuffling around all elements. I don't know the details. Autoindexing on colums might also be less efficient, because column elements are not adjacent in memory.
