Subject: MATLAB simulation 1D 

After my fail attempt on simulating those thin layers of coatings on COMSOL, I turned back to MATLAB.

The model is based on 1-D heat equation. I haven't add the effect of coating yet. This will be done soon after.

I assume no radiative loss on any surface, only the effect from AC input. The boundary condition is sinusoidal on the

reflecting surface of the mirror, and no heat flow at the back of the mirror (dT/dz = 0).
