- Determine and install a supported compiler for your MATLAB release.
- Execute 'mex -setup' command to configure visual studio compiler for C/C++ compilation.
- Use the MATLAB ‘mex’ command to build a binary MEX file from your C/C++ source files.
- Use your binary MEX file like any MATLAB function.

I have successfully installed MinGW-w64 C/C++ compiler as add-on and executed the command 'mex -setup'. I have kept the folder contains C++ files in the current path. What next to do? This is the first time I am working with mex. Thanks for any help in advance.

To create and use a MEX file, you may need to:
You can use the following commands to obtain a copy of the file, ‘timestwo.c’ on your local installation of MATLAB, and create a MEX file from it:
copyfile(fullfile(matlabroot,'extern','examples','refbook','timestwo.c'),'.','f')
mex timestwo.c
Upon successful creation of a MEX file, you should see something like:
Building with 'MinGW64 Compiler C '.
MEX completed successfully.

After generating MEX file, we can call the mex function by calling its name and passing input arguments.
For the above provided example, You can run the generated mex by executing following command
timestwo(2) % Input argument can be any value
