Call Functions in Windows Interface to C++ Compiled Library

Set MATLAB Path to Interface and Library Folder

If you created the matrixOperations interface in the example Header and C++ Compiled Library Files on Windows, then you can use it in the following example. Navigate to the folder you used to create the matrixOperations.dll interface file.

Put the compiled library file in the folder with the MATLAB^® interface file. Uncomment and execute one of these statements based on your selected compiler.

%copyfile(fullfile(productPath,"win64","mingw64","*.dll"),".","f")
%copyfile(fullfile(productPath,"win64","microsoft","*.dll"),".","f")

Call addpath on the folder containing the interface file.

View Help

At the MATLAB command prompt, display help for the interface. In the example, the clibgen.generateLibraryDefinition command set the name of the interface to matrixlib. Type this command to load the interface.

Call Library Functions

Test the functions in the interface. For example, type:

matObj = clib.matrixlib.Mat;   % Create a Mat object
intArr = [1,2,3,4,5];
matObj.setMat(intArr);     % Set the values to intArr
retMat = matObj.getMat(5)  % Display the values

retMat =
