lookup table

[echomice]

hey, I'm stuck on making my loopuptable work.

here is the requirement

I have a constant 2d array table, as following:

1 1001

2 1002

3 1003

4 1004

.

.

.

29 1029

the input is dynamic :for example

2

4

9

and I expect the output is

1002

1004

1009

I tried several methods but still didnt get success, if there anybody here can give me a help in how to deal with it? maybe an example vi ?very appreciated

cheers~

 From your description, it's not a 2D array at all. It's a 1D array. All you need is the Index Array function and make sure the Index input is an integer.

Why did you post this to the Digital I/O board?

sorry; I think I didnt see this is the Digital I/O board. however, thanks for reply, but the input is an array.

2 4 9, or others like this, it changes everytime. I cant find a way to get the output array~:( looking for help~

I really don't understand what the problem is. What do you mean the input is an array? Is this what you want to use as an index? If so, simply place the Index Array function inside a for loop. Wire the array through the for loop and you will get an array out.

It would be wise to post an image or the actual code you have if you continue to have problems.
