Benefits of Mathworks Tool Chain

MATLAB in General

§  Easy to use programming language

§  Handles large datasets easily

§  Toolboxes allow to scale MATLAB to the needs of specific project Dynamic Modeling/Simulation and Control Design of Dynamics in Simulink §  Graphical user interface

eases design of dynamic system and allows fast control design

§  Hierarchical model with subsystems allow to easily adjust modeling level

§  Component based, components are easily reusable in multiple model/projects

§  Flexible interfaces for post processing of simulation data

§  Simulink models can be easily adjusted to model variants
