Use Prebuilt MATLAB Interface to C++ Library

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

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

`clibArray`	Create MATLAB clib array for C++ library functions (Since R2020a)
`clibConvertArray`	Convert MATLAB fundamental or struct array to MATLAB array of C++ objects (Since R2020a)
`clibConfiguration`	Change execution mode of C++ library interface (Since R2023a)
`CLibraryConfiguration`	C++ library interface environment information (Since 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

Configure C++ Library Interface

Set Run-Time Library Path for C++ Interface
If the C++ library has a compiled library file, then that file and its dependencies must be on your system path or run-time search path (rpath).
Load C++ Library In-Process or Out-of-Process
Execute C++ functions in processes that are separate from the MATLAB process.
