MATLAB Arduino command reference list

Hi,

I am aware of the getting started documentation provided by Mathworks but I am unable to locate a complete list of MATLAB commands for Arduino communication (on top of normal MATLAB commands). Is this because there are no extra commands it is just normal MATLAB but with serial communication?

Cheers,
