Appeler MATLAB à partir de C

Exécuter du code MATLAB^® depuis des programmes C avec mxArray

Remarque

Les fonctions de l’API Engine pour C utilisent la structure de données MATLAB mxArray définie dans C Matrix API. Pour écrire des applications avec les fonctionnalités du C++ moderne, consultez Appeler MATLAB à partir de C++.

Les applications Engine sont des programmes autonomes qui vous permettent d’appeler MATLAB depuis vos propres programmes C/C++ en utilisant MATLAB comme moteur de calcul. Pour créer une application Engine, appelez la fonction mex.

Les applications Engine nécessitent une version installée de MATLAB. Vous ne pouvez pas exécuter MATLAB Engine sur un ordinateur seulement équipé de MATLAB Runtime.

Engine API pour C

`Engine`	Type for MATLAB engine
`engOpen`	Start MATLAB engine session
`engOpenSingleUse`	Start MATLAB engine session for single, nonshared use
`engClose`	Quit MATLAB engine session
`engEvalString`	Evaluate expression in string
`engGetVariable`	Copy variable from MATLAB engine workspace
`engPutVariable`	Put variable into MATLAB engine workspace
`engGetVisible`	Determine visibility of MATLAB engine session
`engSetVisible`	Show or hide MATLAB engine session
`engOutputBuffer`	Specify buffer for MATLAB output
