Sure? What you mention is in site-packages/scipy/integrate/ode.py where
the class ode is defined. But I'm using integrate.odeint (in
site-packages/scipy/integrate/odepack.py) and there is nothing mentioned
about it. odeint is there called like this
import _odepack
[...]
output = _odepack.odeint(func, y0, t, args, Dfun, col_deriv, ml, mu,
full_output, rtol, atol, tcrit, h0, hmax,hmin,
ixpr, mxstep, mxhnil, mxordn, mxords)
BTW, does anyone have experiences with the ode class (and it's vode (or
cvode?) solver) rather than odeint's lsoda?
cheers,
steve
