Aerospace model based designing

Hi everyone...I am doing a project on model based designing of landing gear of an aircraft using MATLAB. So, I would appreciate if anyone of you will help me out in getting started. Please post links for some video tutorials for using aerospace toolbox. I have already seen and understand to some extent the "aeroblk_HL20" demo.
Actually I wanted to make a functional model of landing gear of an aircraft(no particular just general) using MATLAB.
Help is needed as I am new to aerospace field as I am pursuing my Btech in EEE.

Thank you !!!
