Verwenden einer vordefinierten MATLAB-Schnittstelle zu einer C/C++ Bibliothek

Um eine Funktion in einer C oder C++ Bibliothek aufzurufen, verwenden Sie den Namespace MATLAB^® clib

Wenn Sie über eine veröffentlichte MATLAB-Schnittstelle zu einer freigegebenen C/C++ Bibliothek verfügen, dann können Sie diese Klassen und Funktionen direkt in MATLAB nutzen und Daten zwischen MATLAB und C/C++ übertragen.

Funktionen

`clibArray`	Create MATLAB clib array for C++ library functions
`clibConvertArray`	Convert MATLAB fundamental or struct array to MATLAB array of C++ objects
`clibConfiguration`	Set run-time configuration parameters for C/C++ library interface (Seit R2023a)
`CLibraryConfiguration`	C/C++ library interface environment information (Seit R2023a)
`clibIsNull`	Determine if C++ object is null
`clibIsReadOnly`	Determine if C++ object is read-only
`clibRelease`	Release C++ object from MATLAB
`underlyingValue`	Underlying numeric value for C++ enumeration object created in MATLAB
