how to add changing 1D array to 2D array for update

[astroboy]

Hi is there anyone who help me with this knotty problem. How to add the changing 1D array to 2D array?
Pls take a look at my Vi file. Your help will be much appreciated. Pls help modify my Vi file so that I can see it and understand clearly. many thanks in advance.

Well, it's probably easier to put it all in one loop and use a shift register (see attached). Let me know if you have questions.

Hi altenbach. It works great just as I had expected. But some how actually the random numbers are not supposed to be in the 'for loop' with build array.
Becos I am using DAS card to access the signals from 4 channels at a time. That's why the random number act as a channels input of DAS card for build array to build up tha array. And I also use I/O of DAS card to control so that each channel will capture voltage value at a time. I am using Advantech's DAS card.
So how do we do that? I am using while loop too. I am not sure If u have drivers for advantech card, I will attach for you anyway, maybe it will help. Alternatively u can use the other file which you have used. Thanks for your help again.

No, I don't have any DAQ drivers, so I cannot test, but why couldn't you just do the same thing in the main while loop (see attached)?

Hi. I just realise that I can put DAS functions.vi just inside the for loop. Thanks for your help. Without you, I would still be stranded in the mud. Thanks again.
