Finding the Original Index of Elements in a Sorted Array

[Burrito]

Overview

This VI takes an Array, sorts it, and then builds it into a 2D array along with the index of each element in the original array.

Description

This VI uses a for loop and the Search 1D Array function. The Search 1D Array function searches in the original array for each element in the sorted array, and returns the index of that element in the original array. The sorted array and the array of original indexes is then built into a 2D array.

Steps to Execute Code

1.     Download SortIndexArray.vi

2.     Open SortIndexArray.vi

3.     Run SortIndexArray.vi

This VI fails when array elements includes more than one zero's.

That's true; It actually finds the first instance of the number and keeps its index. That means that every duplicate number will have the same index.
