[SciPy-user] Solving Two boundary value problems with Python/Scipy

I don't think that there's a function specifically for boundary value 
ode problems in SciPy, but it is pretty simple to combine an ode solver 
with a zero finder to use the "shooting method."  I'm not familiar with 
how rlab or Matlab does it, but the Scilab "bvode" uses a finite 
difference method.  If the problem isn't too complex, the shooting 
method is easy to set up, and works as well as the finite difference 
method.  (In my vast experience ... well, ok, two applications ... the 
shooting method was more forgiving and less brittle than the finite 
difference method.)

What sort of bvp do you have?
