Implémenter des blocs avec des System objects
Le bloc MATLAB System utilise un System object pour implémenter des algorithmes MATLAB® dans Simulink. Avant d'utiliser un bloc MATLAB System, vous devez disposer d'un System object à associer à ce bloc. Un System object est un type particulier de classe MATLAB spécifiquement conçu pour l'implémentation et la simulation de systèmes dynamiques. Pour plus d'informations sur l'implémentation et la création de System objects, consultez la rubrique Créer des System objects.

Integrate Python GPS Text Message Parsing Algorithms in Simulink
Parse text messages in NMEA GPS format using Simulink® string blocks and Python®. NMEA sentences are used for communication between marine devices, and the model in the example decodes RMB and RMC sentences in NMEA. RMB is the sentence for the recommended navigation data for GPS. RMC is the sentence for the recommended minimum data for GPS sentences.
Convert MATLAB Algorithms of Dynamic Systems into a Simulink Model
Convert MATLAB® code that models a dynamic system using System objects into a Simulink® model. This example maps the dynamic system components defined in MATLAB onto a Simulink block diagram using blocks with similar functionality. Transforming MATLAB code to a Simulink model enhances your modeling experience by allowing you to create a block diagram of the system, simulate the model, visualize the results via graphs and animation, log data, verify and validate, and generate code.
