Hi all,

I have a question wrt.

odeint(func, y0, t, args=(), Dfun=None, col_deriv=0, 
full_output=0, ml=None, mu=None, rtol=None, atol=None, 
tcrit=None, h0=0.0, hmax=0.0, hmin=0.0, ixpr=0, mxstep=0, 
mxhn
il=0, mxordn=12, mxords=5, printmessg=0)

     h0 : float, (0: solver-determined)
         The step size to be attempted on the first step.
     hmax : float, (0: solver-determined)
         The maximum absolute step size allowed.
     hmin : float, (0: solver-determined)
         The minimum absolute step size allowed.

Is it really useful to start with the default values
h0=0.0, hmax= 0.0 and hmin=0.0 ?

Nils
