1D Index Array Extraction

[Chron0]

Hey all,

I'm relatively new to using LabView and cannot figure out how to get this done.

I have 2 arrays, aray A and array B. I want to look up the specific values from Array B by analyzing Array A first and noting what locations, indexes, they are. 

From Array A I am able to locate the locations, but it is in the form of a 1-D array of double. Now that I know the indexes of locations in interest,how do I extract the data from Array B? 

When I try to use Index Array LabView gives the following error, 'source is 1-D array and sink is long'. Any help would be greately appreciated on how I can extract the data points from Array B by having an array of indexes of interest.

Example of what I'm trying to do

Input:

Locations / Indexes: 1  3  4

Waveform Array: 0  2   4  6  8  10

Output:

0  4  6 

Thank you for your time

Arrays are 0 indexed so locations 1,3, & 4 should be 0, 2 & 3 if you want those output values.  Attached is a pic of the code to do this. Be sure to disbale indexing on the data set and allow indexing on the 'location/indices' array.

Thanks a bunch you guys. This was exactly what I was looking for!
