Appeler MATLAB à partir de Python
MATLAB Engine API pour Python propose un package pour que Python appelle MATLAB en tant que moteur de calcul. Le moteur supporte l’implémentation de référence (CPython). Pour plus d’informations sur les versions supportées, consultez Versions of Python Compatible with MATLAB Products by Release (Versions de Python compatibles avec les produits MATLAB par version).
Pour installer et démarrer le moteur, consultez Get Started with MATLAB Engine API for Python.
Pour appeler des fonctions Python depuis MATLAB, consultez Appeler Python à partir de MATLAB.
Les applications Engine nécessitent une version installée de MATLAB. Vous ne pouvez pas exécuter MATLAB Engine sur un ordinateur seulement équipé de MATLAB Runtime.
