Integrate Python Code into Simulink

Integrate algorithms with Python® code into Simulink®

Simulink allows you to implement algorithms designed using Python code. You can implement Python modules in Simulink using the MATLAB Function block, MATLAB System block, or Python Importer. For implementation of simple algorithms, use the MATLAB Function block. For algorithms that require handling of state dynamics, streaming data, and additional block customizations, use the MATLAB System block. Python Importer enables you to import Python modules into Simulink by generating custom blocks for specified functions.

Integrate Python GPS Text Message Parsing Algorithms in Simulink

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.
