This file contains important information about the LabVIEW 2012 MathScript RT Module, including installation instructions, new features, and known issues.
Automating the Installation of NI Products
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.
In addition to the system requirements for the LabVIEW Development System, the MathScript RT Module has the following requirements:
Refer to the LabVIEW Readme file in the labview directory for additional system requirements and supported operating systems for LabVIEW 2012.
Complete the following steps to install the MathScript RT Module.
You can install all of your LabVIEW products—including the MathScript RT Module—using the LabVIEW 2012 Platform DVDs. Refer to the LabVIEW Installation Guide on the LabVIEW Platform DVD 1 for installation instructions and system requirements.
To request additional LabVIEW Platform DVDs, refer to the National Instruments website.
Note: If you purchased this product with an NI Software Suite or NI Product Bundle, use the installation media that shipped with your purchase to install this product.
Complete the following steps to install the LabVIEW MathScript RT Module on Mac OS X.
Delete the following files or directories on the computer to manually uninstall the LabVIEW MathScript RT Module on Mac OS X:
Complete the following steps to install the LabVIEW MathScript RT Module on Linux.
To run a script that uninstalls the MathScript RT Module on Linux, enter the following command:
sh ./UNINSTALL
The LabVIEW 2012 MathScript RT Module introduces the following enhancements and changes.
In the LabVIEW 2012 MathScript RT Module, you can organize data with different types and sizes in a single variable for use in the LabVIEW MathScript Window or the MathScript Node. Every cell in a cell array can store data with a different type and size than the data in the other cells in the cell array. Refer to the MathScript RT Module»Organizing Data with Different Types and Sizes in Variables topic on the Contents tab of the LabVIEW Help for more information about cell arrays.
When you pass a 1D array of strings from the block diagram into a MathScript Node, by default, MathScript pads the strings with spaces until all the strings are the same length as the longest string. In the LabVIEW 2012 MathScript RT Module, you can pass a 1D array of strings into a MathScript Node and right-click the input terminal on the node to select String Representation»Cell Array. When you specify to use cell arrays, MathScript maintains the length of each string in the array without adding any spaces. Refer to the MathScript RT Module»Using MathScript Nodes»Debugging MathScripts»Passing Data in and out of the MathScript Node topic on the Contents tab of the LabVIEW Help for more information about passing cell arrays, and other data types, in and out of the MathScript Node.
The MathScript RT Module 2012 includes the following new functions. You can use these functions in the LabVIEW MathScript Window or a MathScript Node.
Refer to MathScript RT Module»MathScript RT Module Functions book on the Contents tab of the LabVIEW Help for more information about built-in MathScript functions.
The expm1 function computes the base e exponential of the input elements minus 1.
You can access the software and documentation known issues list online. Refer to the National Instruments website for an up-to-date list of known issues in the MathScript RT Module.
The following items are the IDs and titles of a subset of issues fixed in the LabVIEW 2012 MathScript RT Module. This is not an exhaustive list of issues fixed in the current version of the MathScript RT Module. If you have a CAR ID, you can search this list to validate the issue has been fixed.
| ID | Fixed Issue |
|---|---|
| 242487 | Cannot drag multiple variables between local and global categories |
| 253318 | The ode_bdf15 function takes too long to execute |
| 279449 | Save All also tries to save the plot window generated by the plot function |
| 281000 | LabVIEW MathScript hangs when loading a script with a large model |
| 309671 | MathScript does not handle an enum inside of a struct correctly when passed into a MathScript Node |
| 336366 | Assigning an empty matrix to a field of a structure returns error -90042 for an array of structures |
Refer to the MathScript RT Module book on the Contents tab of the LabVIEW Help for more information about the MathScript RT Module.
Refer to the labview\examples\MathScript directory for LabVIEW examples for the MathScript RT Module. 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.
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.
