Use Prebuilt MATLAB Interface to C++ Library

To call a function in a C++ library, use the MATLAB® clib package

If you have a published MATLAB interface to a C++ shared library, then you can use these classes and functions directly in MATLAB, passing data back and forth between MATLAB and C++.

Functions

clibArrayCreate MATLAB clib array for C++ library functions
clibConvertArrayConvert numeric MATLAB array to array of C++ objects
clibIsNullDetermine if C++ object is null
clibIsReadOnlyDetermine if C++ object is read-only
clibReleaseRelease C++ object from MATLAB
underlyingValueUnderlying numeric value for C++ enumeration object created in MATLAB
