# MTT

## Model Transformation Tools

### Bond-graph based modeling tools

MTT is a set of tools for modeling dynamic physical systems using the bond-graph methodology and transforming these models into representations suitable for analysis, control, and simulation.

## Introduction

- MTT uses and generates `.m` files for [GNU Octave](https://www.octave.org/).
- MTT is mainly built on the [GNU](https://gnu.org/) set of tools.
- MTT uses the algebraic package [REDUCE](https://reduce-algebra.sourceforge.io/).
- MTT is based on the bond graph language; general bond graph information is available from [The Bond Graph Compendium](https://www2.engr.arizona.edu/~cellier/bg.html) homepage.
