[SciPy-user] PyDSTool and SciPy (integrators)

I am very interested in getting spline support to a point where it
could be used as a more accurate way of representing solutions to
ODEs. I will certainly use it in my Trajectory class if you give it a
similar interface to that already used by interp1d.

In case this can help in your problem, our current interface to the
H&W codes allows you to specify time points at which the integrator is
guaranteed to step on to as it goes along.
If someone is willing to help improve the low level interfaces to the
H&W codes by exposing internal information like the polynomial
coefficients for the dense solution then I would include that and
other trajectory-related data in our ODE support.
