why signature of func in odeint != ode ?
Why signature of func in odeint is swapped (y,t0 -> t0,y) with respect to func in ode ? It would be nice to have same signature in order to be able to play with both of them more transparently. Details from docstrings: scipy.integrate.odeint: ---- Inputs: func -- func(y,t0,...) computes the derivative of y at t0. ---- scipy.integrate.ode: ---- where f and jac have the following signatures: def f(t,y[,arg1,..]): return <f(t,y)> ---- Is there a reason for this or is it just a little defect?

Legacy -- I'd guess the two interfaces were written by different authors. I'm not sure if this API break can be made the moment. One possible way forward could be to deprecate both `ode` and `odeint` and write a new unified interface for LSODA, *VODE, etc. -- Pauli Virtanen

I believe Gabriel Gellner had started trying to do this, but his project seems not to have any code online when I just checked. https://launchpad.net/pyode Fixing this with a unified interface would be an important milestone towards scipy 1.0 -Rob
hi, another option that comes immediately to mind is to use SWIG to expose your C++ code to python. That is what we are doing routinely in my work. HTH, Johann Rob Clewley wrote:

So I assume it is OK to file a ticket to the SciPy trac (792): http://scipy.org/scipy/scipy/ticket/792 Please review it and add any missing info. Regards, Emanuele
