Description

This document shows three ways to do a simple mathematical analysis using LabVIEW. The three methods shown in this example are:

- Using the LabVIEW Math libraries (simple example ODE LabVIEW.vi)
- Using MATLAB Script Node (simple example ODE MATLAB.vi)
- Using MathScript Node (simple example ODE MathScript.vi)

If you are interested in a comparison of some of these methods, particularly to see the differences between using the MATLAB Node and the MathScript Node, see this page: Moving to MATLAB Script Nodes from MathScript Nodes in LabVIEW

Required software for Windows:

- LabVIEW 2018 (32-bit) or later
- LabVIEW MathScript Module (32-bit) or later
- MATLAB 2018a or later

No hardware required.

**Installing the examples and setting the path in MATLAB:**

Place the following three example benchmark VIs and supporting script (from the **Example Benchmarks for MATLAB Script and MathScript** zip file) into the **Documents > LabVIEW Data** folder on your Windows computer:

- simple example ODE LabVIEW VI
- simple example ODE MATLAB VI
- simple example ODE MathScript VI
- secondord.m

Also make sure that you add the path for the **LabVIEW Data** folder to your MATLAB environment on the same machine.

**Running the example VIs:**

You can run each example VI and observe the results.
