Integrator Argument Passing

[jrleeman]

Allows passing of arguments to the integrator through the solve method. This is useful for things like setting the max step size (hmax) on problems that are particularly unstable. Resolves #5

My only question would be whether you still want abserr and relerr to be attributes on the class, or whether they should go through the same mechanism. You could set defaults if they're not passed in:

odeint_kwargs = dict(rtol=1e-12, atol=1e-12)
odeint_kwargs.update(kwargs)

si.odenit(..., **odeint_kwargs)

So the args start with the defaults, then are overridden by any that are passed in.

Ah. I was wondering what the best way to handle that is. I implemented it in the last push. Also fixed some of my bad spacing issues. How does this look?

[dopplershift]

Looks like someone pep8/flake8 -ed the code. :)

Everything looks good to me.

Yeah, I was bad about that. Will have to do some more cleaning as things get finalized. Some one the lines are pushing 110 chars.

I extended the limit to 90/95 characters in my projects, though I try to keep shorter.
