Call Functions in C++ Compiled Library
The publisher of your MATLAB® interface to a C++ library provides you with instructions for installing the interface file and any dependent library files, if required. The publisher might give you dependent library files, ask you to install libraries from an external source, or provide a link to all relevant files. If the publisher created a toolbox using MATLAB Add-Ons, then this information might be found in the Getting Started Guide available through the Options menu for the toolbox in the Add-On Manager. If you need more information or cannot find a Getting Started Guide, then contact the publisher. For details about add-ons, see Manage Add-Ons.
The name of the interface file for library
ext is platform-specific —
.dll on Windows®,
.so on Linux®, or
.dylib on macOS.
Set Run-Time Path
MATLAB looks for the interface file on the MATLAB path and the dependent library files on the system path or run-time search path (rpath). If the publisher gives you dependent library files, you can put them in the same folder as the interface file. Alternatively, to add them to the system path, see Set Run-Time Library Path for C++ Interface. For information about locating dependent libraries, see Missing or Incorrectly Installed Run-Time Libraries.
Set MATLAB Path
addpath on the folder containing the interface file.

To call a function
funcname in C++ library
with input arguments
arg1,arg2,... and output argument
retVal, use the MATLAB
clib package. MATLAB automatically loads the library when you type:
retVal = clib.libname.funcname(arg1,arg2,...)
After MATLAB loads the library, you can use tab completion to view the members of the
