Gaussian beam propagation package.
Eugeniy Mikhailov
2012


Initially developed by Eugeniy Mikhailov with first files dated by Jun 2006,
but it was started even earlier.

Can treat lenses and empty spaces (with a given refraction index). And able
to calculate Gaussian beam propagation via ABCD matrix formalism.

So far it can  propagate Gaussian beam back and force  and compare the beam
profiles after such propagation.

For a quick demo run:
```  solution_visualization.m

It expects that  script trial_solution.m sets beam  initial, final Gaussian
beam parameters, and  optical elements. See for an example  of such file in
``examples/trial_solution.m.example``.
