# What is Mathematica's equivalent to MATLAB's Simulink?

MATLAB has Simulink and Simscape, Maple has MapleSim and Scilab has Xcos. What is the equivalent product for Mathematica?

From the user perspective the conceptual difference between Simulink and SystemModeler is how the analyzed system is described. SystemModeler (WSM) works at the component level while Simulink works at the "block diagram level". This means that the user defines how the components are connected and WSM is responsible for the development and solution of the equations. With Simulink one needs to provide the behavioral description (transfer functions) of each block and the system.

@WalkingRandomly - and no one can blame them doing so, since object based modeling turns out becoming more and more popular in a lot use cases. However, I would not suggest it to someone really comfortable with Simulink, especially not when working with e.g. signal-proceccing, control theory or the like. (While the capabilities of Mathematica in both mentioned fields are rather nice indeed - Version 9 looks even more promising with build-in functions like PIDTune) –  Sascha Dec 2 '12 at 10:46
