One Product For All Types Of Math

The base product provides all the math functionality. No need to purchase any additional toolboxes for signal analysis, control design, robust design, etc.

Develop Algorithms Rapidly

A comprehensive toolset for rapid development of custom numerical code. Develop solutions faster than with spreadsheets or traditional programming languages such as C/C++

Robust Design Exploration & Verification

Compose’s Open Matrix Language (OML) is incredibly easy-to-use and compatible with Industry standard numerical math languages (eg: Octave). The Interactive Development Environment (IDE) lets you quickly debug code for streamlined troubleshooting of errors



Powerful and Flexible Programming

Matrix Based Data Structure
Compose open matrix language (oml) provides a matrix based, fully interpreted data structure including literals, data types, strings, variables and assignments, indexing, operators, expressions & statements, flow of control & looping, workspace & scoping rules, functions, error & warning I/O.

Compatible with Octave
Compose’s OML is compatible with Industry standards such as Octave. The language is extremely easy to learn and can also be used for batch mode execution.

Integrated Development Environment

Script Editor
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.

Command Window
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.

Variable Browser
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.

Multi-language Environment

Powerful Debugger
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.

Extensive Math Libraries

Differential Equations

Signal Processing

Statistical Analysis

And many more math libraries!



Support for Linux OS

Compose 2017 is now available on Linux platforms such as Red Hat/CentOS 6.6 & 7.2 as well as Suse 12 SP1

Edit, Execute & Debug Python Scripts In Compose!

Compose 2017 Integrated Development Environment (IDE) supports Python as a new scripting language. This allows you to easily edit, execute and debug Python scripts directly within the Compose user environment

Support for GUI Commands

Compose 2017 offers new GUI commands to create interactive UI directly from Open Matrix Language (OML) scripts. Standard GUI components (button, entries, list box, etc.) can be arranged and connected to user functions for interactive data processing


The Next Steps

What do our Customers say about us?

“I am very satisfied with Origin. I think Origin is an excellent plotting tool. Its capabilities are vast, diverse, and beyond my needs. I appreciate the fact that almost anything on a plot can be adjusted according to a desired preference.”

Matthew D. Sena - Sandia National Laboratories

The training session has been invaluable. Your expertise and your patience are exemplary. It cannot be easy to teach a 75 year old new tricks but you have done so with the utmost understanding. The software is extraordinarily powerful: you have explained how to use it in simple and understandable terms.


Excellent tutor – very clear, very impartial, simply excellent.

The Origin software has excellent statistics and is VERY user friendly.
