Seeking help in MATLAB code of EFGM for CFD problems for boundary condition implementation using Penalty method

Implementing J. Dolbow T. Belytschko MATLAB code of EFGM for CFD pronlems where more than one partial differential equations are involved such as continuity, momentum and energy equations. 

Can anaybody share the MATLAB code for a heat transfer problem of EFGM method using Penalty method for implementing boundary conditions.

Thanks & regards
