Call Functions in Interface to matrixOperations C++ Compiled Library on Linux

To run this example, follow the instructions in Header and C++ Compiled Library Files on Linux to create the matrixOperations interface.

Set MATLAB Path to Interface and Library Folder

Navigate to the folder you used to create the matrixOperations interface file.

Put the compiled library file in the folder with the MATLAB® interface file.

copyfile(fullfile(productPath,"glnxa64","*.so"),".","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 =

  1×5 int32 row vector
