Building C++ S-Functions

Use the MATLAB mex command to build C++ S-functions exactly the way you use it to build C S-functions. For example, to build the C++ version of the sfun_counter example, enter

```
mex sfun_counter_cpp.cpp
```

at the MATLAB command line.

Note The extension of the source file for a C++ S-function must be .cpp to ensure that the compiler treats the file's contents as C++ code.
