sorting a very large 2D array

[Jen]

Hi,
I'm looking for a way to sort a (16 x 4001) 2D array. There is a solution posted for an n x 2 array. However, it won't work for this large one. Could someone help me? Thanks!!!

Jen,
I'll let you double-check it, but attached is a 'Sort 2D Array' VI. Its from NI, and as far as I can tell, it should handle your task. If not, it may offer some ideas.
Good luck with it, Doug

Thanks Doug! But unfortunately, I can't use it because I only have LabVIEW 5.0. Thank you for the suggestion though. 😃

Hello,
could you tell us what you mean by sorting a 2D array? This seems to be abiguous to me.

I meant that I wanted to sort a 2D array by one of its columns. Kind of like how you would sort a block of data in Excel by one column.

You could use one of those "standard"-algorithms such as bubble-sort or
quick-sort. It isn't fast, but it works.

A very simple way is to convert the 2D array into a 1D array of cluster of
1D array (in a For Loop, bundle the indexed 1D array). Sort the 1D array
of clusters and reconstruct the 2D array (unbundle in a For Loop).

Here is the example file Doug attached in his answer but for LabVIEW version 5.0. Hope this helps. /Mikael

THANK YOU! 😃 this is perfect.
