在 MATLAB Online 中打开

Configure mex compiler either C or C++ by using MATLAB command in the command window

mex –setup C / C++

This will automatically set to default C / C++ compiler in the hardware if only one compiler is present else it displays a list of compilers and a compiler has to be chosen.

Create a gateway routine mexFunction in the main file and include mex.h header file.

Call the main function inside the mexFunction.

Create a MATLAB executable to the main function by using MATLAB Command

mex main.c

Run the executable (main) in the command window

The above documentation provides a C-Mex standalone example for gateway routine mexFunction implementation
