Overview
This code allows calculating an integral using the Time Domain Math Express VI.

 

Description
This code takes an integral of the input array. The Time Domain Math Express VI is set to Integral. The express VI calculates the integral using the index of the array as delta time. To calculate the actual sum under the curve, the result from the express VI must be divided by the sampling rate.

 

Requirements
LabVIEW Base Development System (or compatible)

 

Steps to Implement or Execute Code
1. Select the Input Data
2. Run the VI
3. Observe the data on the graph.
4. Check the result on the indicator
