Plane file build on matlab

Please, can anyone help me to find Plane.m file on MATLAB code on GitHub… like this Copter.m file on this site SITL: update MATLAB example · ArduPilot/ardupilot@f5e98a6 · GitHub .

or

how can I convert SIM_Plane.cpp file in SITL folder to SIM_Plane.m file on matlab.

thanks
