Simulink Simulink is a graphical programming environment for modeling, simulatingand analyzing multidomain dynamical systems. Its primary interface is a graphical block diagramming tool and acustomizable set of block libraries. It offers tight integration with the rest of the MATLAB environment and caneither drive MATLAB or be scripted from it. Simulink is widely used in automatic control and digital signal processing formultidomain simulation and Model-Based Design.POLYTECHNIC UNIVERSITY OF BARIDEI - Department of Electrical and InformationEngineering

Why Simulink? Simulink, makes simulations easier to achieve, by using blocks thatcorrespond to codes you do not see. With Simulink, the model of the system you want to simulate is morereadable, because it is represented by graphics. You can use Matlab to simulate a system, but you have to program your ownroutines added to the ones that are provided by Matlab. Simulink easily allows to simulate hybrid systems that include both continuousand discrete blocks.POLYTECHNIC UNIVERSITY OF BARIDEI - Department of Electrical and InformationEngineering

Why Simulink? Simulink easily allows to design andsimulate complex state machines and flowcharts. Coupled with another of MathWorks’sproducts, Simulink can automaticallygenerate C source code for real-timeimplementation of systems. Simulink Real-Time (formerly known as xPC Target), together with x86-basedreal-time systems, is an environment for simulating and testing Simulink andStateflow models in real-time on the physical system.POLYTECHNIC UNIVERSITY OF BARIDEI - Department of Electrical and InformationEngineering

Why Simulink? Simulink also supports specific embedded targets (e.g. Arduino, Raspberry).POLYTECHNIC UNIVERSITY OF BARIDEI - Department of Electrical and InformationEngineering
