Hey there,

I am a big fan of what you are trying to do here.  I my educational background is in physics and mathematics.  When in graduate school Mathematica was a huge help in solving the tougher problems analytically but is ridiculously expensive.  I am looking for a python open-source project to get involved in and this one is right up my alley.  I have not used your package yet so I'd be willing to start with some bug fixes to prove my worth.

Have you guys implemented partial differential equations yet?  If not, that will set this package on fire!!

Cheers,

Justin

There is limited analytical PDE solver, but this is not very practical. If numerical PDE solution, that area is pretty well established, even in python.

I'm not sure if coupled ODEs are implemented yet but the easiest way
to tell is to try dsolve() on one (or classify_ode()) and see if it
works.

Hi,

Some systems of ODEs are implemented, so therefore some coupled ODEs should be handled. Support was implemented as part of a GSoC 2014 project that I helped mentor. There are definitely some bugs and work stalled on some of the non-linear systems because of bugs in the single ODE solver. Overall, it’s not been used much so I’m sure that there’s bugs to work out that haven’t been found.

I’d really like to see some attention put to it because no real work has been done on it since the GSoC project aside from some doc cleanup.

Cheers,

Tim.

Hi all,

I have sent free time this week looking through the package and I must say before continuing this package is extremely impressive.  I am glad the math/physics community has taken the time to work on this; I mean, Clebsh-Gordan coeffients!  This is awesome.

Now, to get started I really think I should start with some bug fixes.  There was one coupled linear, homogeneous ODE that comes to mind (came across it in grad level quantum mechanics, solved simply by substitution but takes a while to realize) that I I'll run through the solver.  My first commit will probably be a number of not so simple coupled ODEs with different solve techniques to stress the solver.  I am on the job market right now so it might be the weekend before I make the commit.  We can continue from there.  I hope this helps.

Cheers,

Justin

Fixing bugs is definitely a good place to start.
