MathScript Features

MathScript Feature Description

Powerful Textual Math Over 650 built-in functions for math, signal processing and analysis

Math-Oriented Syntax and Datatypes

Matrices and arrays are fundamental datatypes. Largely support vectorized operations

Compatible Generally compatible with the widely used m-file script syntax

Extendible Define custom functions

Part of LabVIEW Does not require third-party software to compile and execute

Programmatic LabVIEWInterface

MathScript Details

• Part of the Full, Professional, Student and Evaluation editions of LabVIEW, for Windows platforms only (no Linux, Mac, RT, etc.)

• MathScript is NOT a standalone replacement for alternative technical computing software– Third party toolboxes are not supported– Some commands and variable types are not supported

Programmatic Math with the MathScript Node

• Combine graphical system design with textual math• Deploy with LabVIEW graphical programming• Implement equations and algorithms with text

Goal: Multiple Programming Approaches

Integrate math with real-world I/O and instrument control

Add interactive user interfaces to your algorithms

Freedom to choose the best approach Reuse your existing code

Demo: MathScript

Working with Graphical and Textual Approaches in LabVIEW

• Always consider both• Prototype and instrument your math algorithms• Use LabVIEW features through graphical programming • Take a mixed approach to combine graphical and textual

benefits• Work within a single environment to simplify and reduce cost• Reuse your existing m-files

History of 3D in LabVIEW

• LabVIEW 5.1:– First 3D Graphs available– ComponentWorks controls based on

ActiveX

• LabVIEW 7.1:– First 3D Picture Control software– Separate download– No technical support offered

3D Picture Control

• Create 3D scenes using picture control VIs• Control object motion, size, and color using OpenGL• Import objects from design tools (VRML, STL, ASE )

How Does it Work?

• Introduction to API– Geometries

• Box, Cone, Cylinder, Height Map, Mesh or Sphere

– Object• Create or Find object

– Transformations• Translate, Rotate or Scale objects

– Helpers• Color, Light, Window, Texture, etc.

– File Loading• Import ASE, STL or VRML files

– Further functionality available through Property and Invoke Nodes

Benefits of New 3D Picture Control

• Easy to use API• Powerful

– Hardware acceleration supported for Scene Window– Leveraging scene graph technology*

• Multi-OS support– Mac, Linux and Windows

*OpenSceneGraph (www.openscenegraph.org)
