Build MATLAB Interface to C++ Library

To create a MATLAB^® interface to a C++ library, use the MATLAB clibgen package

To build (publish) a MATLAB interface to a C++ library, call clibPublishInterfaceWorkflow. For an overview, see Steps to Publish a MATLAB Interface to a C++ Library.

For information about calling functions in the library from MATLAB, see Use Prebuilt MATLAB Interface to C++ Library.

Functions

`clibPublishInterfaceWorkflow`	Publish interface for C++ library in the Live Editor (Since R2023a)
`clibgen.generateLibraryDefinition`	Create definition file for C++ library (Since R2019a)
`clibgen.buildInterface`	Create interface to C++ library without definition file (Since R2019a)

Generate definition file for C++ interface library in the Live Editor (Since R2023a)
