Rapid algorithm development

A comprehensive set of tools enable rapid development of custom numerical code. The matrix-based language, authoring and debugging tools along with access to a broad set of math libraries and utilities not only covers a wide range of your needs but also enables you to explore multiple approaches and find solutions faster than with spreadsheets or traditional programming languages such as C/C++. Easy diagnosis of code through interactive debugging reduces development effort.

Robust design exploration & verification

The Open Matrix Language (OML) is not only incredibly easy to use, but also compatible with industry standards such as Octave. The interactive desktop environment in Compose allows users to quickly debug code thus allowing for streamlined and faster troubleshooting of errors without the need to embed diagnostic statements or code.

Easy engineering data access & processing

There is a built in suite of comprehensive engineering calculations and CAE data, including result readers, to provide quick access to a large set of data formats for pre- and post-processing needs. Data can then be exported into various formats for easy import into Altair HyperWorks or other third party products.

Powerful and flexible programming

  • Matrix based data structure

  • Fully interpreted

  • Compatible with industry standards

  • Batch-mode execution

  • Literals, data types, strings, variables and assignments, indexing

  • Operators, expressions and statements, flow of control and looping

  • Workspace & scoping rules, functions, error & warning I/O

Integrated Development Environment

  • A fully featured command window with command completion, code editing and display print command outputs during script execution from the editor allowing for visual and interactive code inspections during runtime

  • Modern script editor with syntax highlighting, smart indentation, collapsible sections including code folding, bookmarking, searching and toggling to display on/off line numbers

  • Script editor also allows you to split the screen into multiple views for more interactive authoring and execution

  • Powerful debugger with options to easily monitor variable values via watch window, track paths traced while executing scripts via call stack window and display all breakpoints in the debugging session via the breakpoints window

  • Intuitive project browser with a hierarchical structure of all the scripts, plots, and matrices for easy navigation

  • File browser allows direct access to existing program files on disk

  • Variable browser displays all the user-generated and global workspace variables including their name, value, type and scope. Options to easily monitor variable values during debugging

  • Command history window not only displays all commands entered while programming, but also enables quick execution with support for double-clicking on each command or drag/drop into the command window
