Overview
This example VI creates a Sub-Array based on whether or not values are above or below a threshold.

 
Description
10 random doubles are generated and then compared to a user-defined threshold. The user picks if the values must be above or below. Then a sub-array is built based on wether or not the values are above or below the threshold, based on user input. Shift reigsters are used to store the sub-array as it builds. Before the first loop, the array is initialized. The array either stays the same or adds a new value as the loop iterates.

 
Requirements

  • LabVIEW 2012 (or compatible)


Steps to Implement or Execute Code

  1. Set a threshold.
  2. Select whether the values should be above or below. If 'Above?' is True, then the program selects values that are above the threshold. If 'Above?' is False, then the program selects values below the threshold.
  3. Click 'Run'. Random numbers will be generated and a new sub-array built from those random values based on the threshold value.
