[SciPy-dev] dae solvers

[Benny Malengier]

Thanks for the pointer Rob. I knew of Sundials, but interfacing the C code
API from scipy looked more work than just using the old fortran progs with
f2py (there is some code in the ascent package that does interfaces sundials
though, http://ascendwiki.cheme.cmu.edu/Category:Solvers , but that would
mean a round trip python -> ascent api -> sundials ). Guess I should have
googled a bit longer.

As this pysundials is there, I do think it should be integrated somehow in
scipy. What use of ode class and odepack in scipy which interface old
vode/lsode fortran progs when pysundials exists that interfaces sundials and
like that the new cvode and ida solvers?
So perhaps ode.py should obtain a backend to that?  Or should scipy just no
longer offer ode solvers...

Well, I'm not a scipy dev, just my 2 cents. It always amazes me how many
duplication is going on. I'll investigate my options furter and make up my
mind next week on how to proceed.
