parsing array

[Timothy 123]

Suppose I have a 2D array as follows with two columns, and a few rows. Let's call the first column x, and the second one y
x      y
17   1
26   0
45   1
66   1
87   1
95   1
111   0
117   1
472   0
473   1
17   1
For x elements that are repated, I want to add up their corresponding values together, so instead of having two rows with
17   1
17   1,
I want just one row with 17 2.
Is there an easy way to do this. I would also like to get rid of all rows that have a 0 in the y column.

Thank you

Yes, you can do it but with some array acrobatics. Probably not the best way but it does what you want.

Example in 7.1

Thank you,

This is perfect. Just what I was looking for.

I know this was answered for you but the problem caught my attention and I found an alternate solution that may be a bit faster using the aforementioned array voodoo.

I added my code to the original solution for comparison.

Hi,

Thank you for your code. The only thing is I can't open it since I only have labview 7.1 and 8.0. It would be best if you could save it to 7.1 if that is avialable to you.

No problem, here it is in LV 8.0.1

Cheers,
