This example shows how to create a MATLAB® library definition file for the C++ library declared in the header file
matrixOperations.hpp and defined in the C++ source file
Verify Selected C++ Compiler
You can use any C++ compiler supported by MathWorks. To verify that you have a C++ compiler, type:
mex -setup cpp
This example uses the MinGW64 Compiler (C++) for C++ language compilation.
Generate Definition File
Identify the names and paths to the C++ library artifacts. By default, the function uses
the name of the header file (
matrixOperations) as the name of the library
productPath = fullfile(matlabroot,'extern','examples','cpp_interface'); hppFile = 'matrixOperations.hpp'; cppFile = 'matrixOperations.cpp';
Generate the definition file. MATLAB creates the definition file
clibgen.generateLibraryDefinition(fullfile(productPath,hppFile), ... "SupportingSourceFiles",fullfile(productPath,cppFile), ... "OverwriteExistingDefinitionFiles",true, ... "ReturnCArrays",false) % treat output as MATLAB arrays
C++ compiler set to 'MinGW64 Compiler (C++)'. Definition file definematrixOperations.m contains definitions for 10 constructs supported by MATLAB. - 5 constructs are fully defined. - 5 constructs partially defined and commented out. To include the 5 undefined constructs in the interface, uncomment and complete the definitions in definematrixOperations.m. To build the interface, call build(definematrixOperations).
MATLAB creates the definition file

Open Definition File
Open the generated library definition file by clicking the link in the output message. Then continue with the next step.
