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
