Find Minimum Value in Array, Remove it, Average Remaining Values in LabVIEW

[Will_S.]

Overview

This example demonstrates two methods of searching an array of values for the minimum value. Then removing the minimum value from the array and averaging the remaining values.

Description

The Find Lowest Value in Array Take Average VI performs the following steps:

1. The VI searches the array for the minimum value and the index of that minimum value.
2. Deletes the minimum value element from the array and calculates the number of elements in the array. 
3. The VI then divides the resultant array by the number of elements.

The Find Lowest Value in Array Take Average Modified VI performs the following steps:

1. The VI searches the array for the minimum value, adds all the values of the array together, and calculates the number of elements in the array. 
2. The VI then subtracts the minimum value from the sum of the array and divides this result by the number of elements in the array minus one.

Steps to Implement or Execute Code

1. Download and open the original or modified example
   
2. Initialize the array with the values you wish to search or use it as a SubVI
3. Run the VI and see the average value
   

Requirements to Run

Software

Thanks for posting!

I wonder if you know that the entire left-hand side of the VI (up to and including "Search 1D Array") could be replaced by the single function "Array Max & Min" found in the array palette, which returns not only the minimum, but its index as well.

I was thinking the same thing when I left my comment, but was too afraid to say...

See attached.  I runs 4-5 times faster on large arrays.

BOOM!  Nice work!

I have no idea how I missed that function....oh well, thanks for the tip!
