how do I stack one dimentional arrays

[curt_dvonch]

I have a function, IMAQGetRowCol, which extracts a row of pixels from an image and outputs it as a 1D array.  I have the function in a loop, so that it extracts a row from each image frame.  I want to stack row 50 from each frame on top of each other in a 2D array.  For example, if row 50 of frame 1 is {43 42 56 56 75}, and row 50 of frame 2 is {55 32 42 45 67}, then I want my final output to be

{43 42 56 56 75

 55 32 42 45 67}

This assumes I only have 2 frames.  3 frames would result in 3 rows in the final output, 4 in 4, etc.

How can I accomplish this?

Have you looked at the Build Array function?

Hello,

if I understand correctly, You only have to connect the row output to the loop border and make sure that the auto-index option it's enabled.

I tried smercurio's method and, after the loop finished, I got the very last line of pixels in a 1D array only as my output.  I need a 2D array with one line from all frames included.

Jorge's method worked perfectly, however I wonder if I can accomplish the same thing inside the loop, without having to wait for it to end?

Also, I'm using LabVIEW 8.0, so please save as that version if you include an example VI.

Thanks.
