Stellar structure equations in Matlab?

Does anyone have a Matlab file for solving the stellar structure equations that they wouldn't mind passing along? I'm trying to settle an argument with a friend that they can't really be used to describe nuetron stars and I don't have much programming experience.
Thanks, Alex

Stellar structure equations in Matlab?
How do you plan on applying the stellar structure equations to a neutron star though? It's not like a neutron star has all the same input terms as a regular star, but a different result arises due to different physics. The input terms would all (almost all) be different. If you modify the equations enough, you might as well just model a neutron star. I don't see how a matlab file is going to help in this case either...

Nevermind, forget I asked anything.

You can write code for a "cold" neutron star. Take a look at the paper, "Astrophysical APL  Diamonds in the Sky," hosted at http://nicmosis.as.arizona.edu:8000/...DWARF_TOTV.pdf. Although the paper is for a "cold" white dwarf, you'll need to use the equation of state for a degenerate neutron gas instead of a degenerate electron gas. An additional paper to loock at is "Structure of neutron stars with unified equations of state" hosted at http://arxiv.org/abs/1206.6922.
Hope this helps.
