The Simulink® 3D Animation™ product lets you view and interact with dynamic system simulations in a 3-D virtual reality environment. The toolbox links MATLAB® and Simulink® with virtual reality graphics, enabling MATLAB or Simulink to control the position, rotation, and dimensions of the 3-D images defined in the virtual reality environment. The result is a presentation-quality 3-D animation.
Through visualization, the Simulink 3D Animation product provides insight into the dynamic systems that you model in Simulink. You can use these viewing capabilities in automotive, aerospace, communication, biological, and mechanical applications.

MATLAB is a high-level technical computing language and interactive environment for algorithm development, data visualization, data analysis, and numerical computation. Using MATLAB, you can solve technical computing problems faster than with traditional programming languages, such as C, C++, and Fortran.
You can use MATLAB in a wide range of applications, including signal and image processing, communications, control design, test and measurement, financial modeling and analysis, and computational biology. Add-on toolboxes (collections of special-purpose MATLAB functions, available separately) extend the MATLAB environment to solve particular classes of problems in these application areas.
MATLAB provides a number of features for documenting and sharing your work. You can integrate your MATLAB code with other languages and applications, and distribute your MATLAB algorithms and applications.

Stateflow® is an interactive design tool for modeling and simulating event-driven systems. Stateflow provides the language elements required to describe complex logic in a natural, readable, and understandable form. It is tightly integrated with MATLAB and Simulink, providing an efficient environment for designing embedded systems that contain control, supervisory, or mode logic.
Stateflow charts enable the graphical representation of hierarchical and parallel states and the event-driven transitions between them. Stateflow augments traditional statecharts with the innovative capabilities of control flow, MATLAB and graphical functions, truth tables, temporal operators, directed-event broadcasting, and support for integrating hand-written C code.
You can automatically generate C code from Stateflow charts using Stateflow Coder (available separately).
