LabVIEW MathScript is a text-based environment you can use to write functions and scripts. You can process scripts using LabVIEW MathScript in the LabVIEW MathScript Window or a MathScript Node.

Use the LabVIEW MathScript Window to edit and execute mathematical commands, create mathematical scripts, and view numerical and graphical representations of variables. Select Tools»MathScript Window to display this window.

Use the MathScript Node to execute your LabVIEW MathScripts and other text-based scripts on the block diagram using the MathScript RT Module engine. You can save scripts that you create in the LabVIEW MathScript Window and load them in the MathScript Node and vice versa.

Accessing the Help

Refer to the LabVIEW Help, accessible from Help»LabVIEW Help, for information about the MathScript RT Module.

Finding Examples

Select Help»Find Examples from LabVIEW to launch the NI Example Finder. LabVIEW examples for the MathScript RT Module are located in the labview\examples\MathScript directory. You can modify an example VI to fit an application, or you can copy and paste from one or more examples into a VI that you create.

Automating the Installation of NI Products

You can automate the installation of most NI products using command-line arguments to suppress some or all of the installer user interface and dialog boxes. However, starting with the August 2012 releases (products using NI Installers version 3.1 or later), you may need to perform additional steps before or during a silent installation of NI software.

If the NI product you are installing uses Microsoft .NET 4.0, the .NET installer may run before any NI software installs and may require a reboot before the installation of NI software begins. To avoid a .NET reboot, install .NET 4.0 separately before you install NI software.

For more information about automating the installation of NI products, refer to the following KnowledgeBase articles:

How to Use NI Software with Microsoft Windows 8.x

When you install National Instruments software on Microsoft Windows 8.x, you will notice a few additional tiles in the Apps view, including shortcuts to NI application software products such as NI LabVIEW, Measurement & Automation Explorer (NI MAX), and NI Launcher.

Using NI Launcher

NI Launcher helps you find and launch installed NI products. It provides you with a method of finding NI products similar to the Start menu in previous versions of Microsoft Windows. To use NI Launcher, click the NI Launcher tile in the Apps view. NI Launcher launches the desktop and opens a menu containing a list of NI products. Click any NI product to launch it.

Note  NI MAX does not appear as a desktop shortcut when installed on Microsoft Windows 8.x. You can launch NI MAX either from the Apps view or from within NI Launcher.

Pinning Frequently Used Applications

For convenience, you can pin your most-used NI applications, such as MAX, to either the Start screen or the Taskbar on the desktop, as necessary:

Current ApplicationIcon LocationPin to Action

Windows 8.x Desktop Start screenRight-click application and select Pin to Start
Windows 8.x Start screenDesktop TaskbarRight-click application and select Pin to taskbar from the menu bar on the bottom of the screen

Finding All Programs

If you want to find a particular application or related files, such as documentation files, from the Start screen, you can access all installed files from the Apps view. To get to the Apps view, right-click anywhere on the Start screen and select All apps (Windows 8.0) or click the down arrow on the bottom left of the screen (Windows 8.1).
