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
