In Matlab physical layer can be implemented using its mathematical equations. There are many inbuilt functions for fading channels which can be used directly like Rayleigh or you can use AWGN channel also. Starting from data generation to modulations , everything in Matlab can be implemented by finding its logic through mathematical equations and then implement using commands of Matlab.

If the definition of a physical layer is defined by the physical behaviour of a system than the descritpion of the behavior has to be done by the physical equiations. The equations can be solved by matlab with the symbolic toolbox. In case only differential equations are used those equations can be integrated by mathlab or after modelling in simulink simulated.
On the other hand if there is an algorithm to describe the physical behavior the algorithm can be implemented in maltab and calculated.
