视觉论坛的各种资源，除了视觉相关的模块有使用外，大部分的都不会使用，所以仅提供资源不能提供技术支持。资源的下载地址一般会同时提供NI官方地址和百度网盘的下载地址。某些工具包NI的地址失效或没有NI的下载地址，那视觉论坛也没有办法，只能尝试使用百度网盘地址下载；如果百度网盘的下载地址失效过期，可联系论坛客服更新。现在NI的下载服务器对我国IP地址不是很友好，有些时候速度很慢或大的资源下载很容易出错，这样会造成安装过程各种类型报错而无法安装。建议在下载完成后，对下载资源做校验和验证（NI一般会提供MD5或SHA256等），与官方或视觉论坛提供的校验和对比，一致就可以安装，如果不一致，则需要重新下载。视觉论坛早期下载的资源，那时候NI没有这么多限制，基本上都是正常下载的资源；后期下载的资源，都与NI的正确校验和对比过，保证是正确的资源才上传到百度网盘，所以百度网盘的资源基本上是正确的。校验和工具下载地址：

Overview
LabVIEW MathScript is a text-based language 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.
System Requirements
The MathScript RT Module has the following requirements:
(Windows) The MathScript RT Module supports the following operating systems for application development:
Windows 7 (32-bit and 64-bit)
Windows Vista (32-bit and 64-bit)
Windows XP (32-bit)
Windows 2000
Windows Server 2003 R2 (32-bit)
Windows Server 2008 R2 (64-bit)
Note The MathScript RT Module does not support Windows NT/Me/98/95 or the Windows Server non-R2 editions.
Installation Instructions
Complete the following steps to install the MathScript RT Module.
Windows
You can install all of your LabVIEW products—including the MathScript RT Module—using the LabVIEW Platform DVDs. You can find installation instructions for the module along with activation instructions in the following locations:
LabVIEW Release Notes, which are available in your LabVIEW software kit.
LabVIEW Platform DVDs Readme, which is available on the top-level of LabVIEW Platform DVD 1.
To request additional LabVIEW Platform DVDs, refer to the National Instruments Web site.
Mac OS
Complete the following steps to install the LabVIEW MathScript RT Module on Mac OS.
Linux
Complete the following steps to install the LabVIEW MathScript RT Module on Linux.
Log into the system as root.
Insert the LabVIEW MathScript RT Module installation CD. Use mount /mnt/cdrom to mount the CD. On some systems, the CD mounts automatically.
To change the current directory to the mounted CD, enter the following command:
cd /mnt/cdrom
To run the installation script, enter the following command:
sh ./INSTALL
If you encounter the message bad interpreter: Permission denied, the CD might not have mounted with executable permissions. To correct this issue, enter the following command:
/bin/sh ./INSTALL
Accessing the Help
Refer to the MathScript RT Module Functions and Fundamentals»Formulas and Equations books on the Contents tab of the LabVIEW Help for more information about the MathScript RT Module.
Finding Examples
Refer to the labviewexamplesMathScript 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.
New Features
The LabVIEW 2009 SP1 MathScript RT Module introduces the following enhancements and changes to LabVIEW MathScript. The LabVIEW 2009 MathScript RT Module does not contain these features.
Determinism Guidelines
National Instruments has tested a subset of functions and constructs possible in MathScript and found that they typically execute in a bounded amount of time on RT targets when used according to the guidelines in LabVIEW Help. Refer to the MathScript RT Module Functions»Guidelines for Using LabVIEW MathScript in Real-Time Applications book on the Contents tab of the LabVIEW Help for more information about reducing jitter and achieving bounded execution times for applications that contain MathScript Nodes.
New MathScript Functions
The MathScript RT Module includes the following functions of the rt class, which you can use to perform debugging and isolate sources of jitter on RT targets:
rt_debugoutput
rt_loadsend
rt_loguserevent
rt_starttrace
rt_stopsave
rt_stopsend
rt_tickcount
rt_wait
rt_waitmultiple
Performance Improvements
The LabVIEW MathScript Window and MathScript Nodes launch faster due to performance improvements.
LabVIEW MathScripts compile faster at edit time in the MathScript Node due to performance improvements.
Known Issues
You can access the software and documentation known issues list online. Refer to the National Instruments Web site for an up-to-date list of known issues in the MathScript RT Module.
