API, Reference Guides
Overview of external readers and the Altair Binary Format, the generic ASCII reader, running applications in batch mode, using Tcl/Tk commands, translators, and result math.
- Extensions
  Extensions are programs integrated with the application to enhance or extend the user experience.
- External Readers and Altair Binary Format
  Altair Binary Format (ABF) is the standard binary format read by the program. A library called abflib allows you to create files in ABF.
- Generic ASCII Reader
  A generic ASCII reader is now available which allows you to bring custom results directly into HyperView. The Altair ASCII format is useful for reading the results of any in-house or propriety codes which are saved in a generic format.
- Batch Mode
  Batch mode allows you perform a series of operations outside the program interface.
- External Resources
  External resources can be registered in preference files, session files, or Templex files. If an external resource is registered in a program session, it is automatically registered in the session file when the session is saved.
- Python API
  The Python API documentation for HyperMesh applications.
- Tcl/Tk Commands
  The application's scripting interface is a set of Tcl/Tk commands that follow a simple and consistent syntax.
- Translators
  Translators are utilities that are run from the command line of the operating system to convert various types of files into different formats.
- Result Math
  XML commands in the Result Math Module.
- HWC Console
  Record playback workflows in the application.
- HyperMesh Report
- Task Manager
  Use the Task Manager to load an XML file that defines tasks and their attributes.

- Templex and Math Reference Guide
  - Templex Reference
    Templex is a general purpose text and numeric processor which generates output text based on guidelines defined in a template.
    - About Templates
      A template is an ASCII text file containing plain text, Templex statements, mathematical expressions, constants, and variables that Templex processes.
    - Write Templates
      The syntax for Templex statements is similar to that of the C programming language.
    - Variables, Expressions and Formatting
      Learn about variables, expressions, and formatting using Templex.
    - Run Templex
      As well as using Templex from within MotionView and HyperGraph, Templex can also be run in batch mode from the command line of Unix operating systems.

      - '
        Marks text as a comment.

      - automir
        Returns a mirror factor (either 1 or -1) that is value-dependent, either by position of the centroid or the position of the min/max values relative to the x axis.

getvalueatindex

Retrieves a value from a vector.

Syntax

getvalueatindex(vector_name, index)

Input

vector_name: The variable name of the vector to be accessed.
index: The index of the value to be returned.

Example

Template:

{a = 0:10:1}
{getvalueatindex(“a”, 3)}

Comments

This function is equivalent to using the [] operator, but is faster for large amounts of data.
