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
In addition to the system requirements for the LabVIEW Development System, the MathScript RT Module has the following requirements:
Refer to the LabVIEW Release Notes, which are available in your LabVIEW software kit or on the National Instruments Web site, for additional system requirements and supported operating systems for LabVIEW 2011.
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.
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.
Mac OS X
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:
/Applications/National Instruments/LabVIEW 2011/resource/mathscript.rsc
/Applications/National Instruments/LabVIEW 2011/examples/MathScript/
/Applications/National Instruments/LabVIEW 2011/vi.lib/imath/
/Applications/National Instruments/LabVIEW 2011/vi.lib/imathl/
/Documents/LabVIEW Data/InstCache/
/Library/Caches/National Instruments/InstCache/
/Documents/LabVIEW Data/MathScriptVIs/
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/Linux
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
To run a script that uninstalls the MathScript RT Module on Linux, enter the following command:
sh ./UNINSTALL
Accessing the Help
Refer to the MathScript RT Module book 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 2011 MathScript RT Module introduces the following enhancements and changes.
MathScript Support for Structures
In the MathScript RT Module 2010 and earlier, you assign related data to separate variables. In the MathScript RT Module 2011, you define structures, or structs, to organize related data in the LabVIEW MathScript Window or a MathScript Node. You also can wire a cluster to a MathScript Node, where that cluster becomes a structure. Refer to the MathScript RT Module Organizing Related Data in Variables topic on the Contents tab of the LabVIEW Help for more information about structures.
Documentation Addition for Structures
If a MathScript Node contains a warning glyph, LabVIEW cannot determine the data types of any of the variables included in the node. To pass a variable out of the node, right-click the output terminal and select the variable's data type through the Choose Data Type option in the shortcut menu. However, you cannot select a data type for a structure if there is a warning glyph in the MathScript Node. LabVIEW does not allow structure as a possible data type choice, and the output terminal to the node breaks. To pass structures out of the MathScript Node, avoid functions or scripts that cause warning glyphs.
New MathScript Functions
The MathScript RT Module 2011 includes the following new MathScript functions. You can use these functions in the LabVIEW MathScript Window or a MathScript Node:
| MathScript Class | Function |
| basic | deg_to_rad, rad_to_deg |
| communications | padm, pam, qadm, qam |
| filter design | rcos |
| filter implementation | filter_rcos |
| ignored | paintnow |
| linalgebra | reverse_vector |
| matrix | add_noise, padarray |
| plots | compass, eyediagram, is_hold, print, view_image |
| statistics | density_kernel, kurtosis, moment_central, movavg, randint, randsample, skewness |
| struct | is_field, is_struct, remove_field |
| support | menu |
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.
MathScript Function Changes
The MathScript RT Module 2011 includes the following changes to built-in MathScript functions:
The aoch and aowf functions contain a limits input that specifies the lowest and highest limits of a signal.
The iir_butterord, iir_cheby1ord, iir_cheby2ord, and iir_ellipticord functions contain a domain input that specifies whether the output filter is digital or analog.
The interpolate1d function accepts complex sample data.
The load function supports loading structures from files, and the save function supports saving structures to files.
The log2 function includes syntax for splitting input elements into binary mantissa and binary exponent.
The following functions include syntax that accepts a structure containing parameters for the ODE solver:
ode_adams
ode_bdf15
ode_bdf23
ode_radau5
ode_rk23
ode_rk45
ode_rosen
The odepset function includes syntax that returns a structure containing parameters for the ODE solver.
The following functions include enhancements to generating or manipulating 2D and 3D plots:
The contour, contour3d, contouris, and contours functions contain an x input and a y input that specify the surface you are plotting in relation to the x-plane or y-plane, respectively.
The legend function includes syntax for specifying the location of the legend.
The line function includes syntax for plotting lines on a 3D graph.
The plotyy function includes syntax for returning references to the plot area, the line with the left y-axis, and the line with the right y-axis.
The subplot function includes syntax for specifying the location of the subplot.
The text function includes syntax for plotting text on a 3D graph.
The powerof2 function includes syntax for specifying two inputs.
The reshapemx function includes syntax that allows you to specify the size of the array as an input variable.
