Simulink

Simulink is a MATLAB-based graphical programming environment for modeling, simulating and analyzing multidomain dynamical systems. Its primary interface is a graphical block diagramming tool and a customizable set of block libraries. It offers tight integration with the rest of the MATLAB environment and can either drive MATLAB or be scripted from it. Simulink is widely used in automatic control and digital signal processing for multidomain simulation and model-based design.

== Add-on products == MathWorks and other third-party hardware and software products can be used with Simulink. For example, Stateflow extends Simulink with a design environment for developing state machines and flow charts. Simscape is an add-on product that extends Simulink with support for physical modeling. Developed by MathWorks, it enables the modeling and simulation of multidomain physical systems by connecting physical components whose interactions represent domains such as electrical, mechanical, thermal, and fluid systems. Simscape models can be combined with standard Simulink block diagrams, allowing the simulation of systems that couple physical dynamics with control algorithms and signal-based components. Coupled with another of their products, Simulink can automatically generate C source code for real-time implementation of systems. As the efficiency and flexibility of the code improves, this is becoming more widely adopted for production systems, in addition to being a tool for embedded system design work because of its flexibility and capacity for quick iteration. Embedded Coder creates code efficient enough for use in embedded systems.
