C++ Libraries
If you have a C++ shared library that exports functionality that can be called from another application, then you can use these classes and functions directly in MATLAB, passing data back and forth between MATLAB and C++.
To get started, you first must publish an interface library, using the following.
A shared library file —
.dllon Windows®,.soon Linux®, or.dylibon macOSOne or more header files that contain declarations of all the functions exported by the library
An import library file (optional) —
.libA MATLAB-supported C++ compiler
If you already have the interface, then you can call functions in the
library using the
clib.
syntax. The library must be on your system or run-time search path.
For more information, see Call Functions in C++ Shared Library.packagename
If you call functions in C libraries using the calllib
function, then see C Libraries.
If you write C/C++ functions in MEX files, then see C++ MEX Applications or C MEX File Applications.
