SciPy 0.6.0 API Documentation Generated by Endo, 2007-10-17

User-friendly interface to various numerical integrators for solving a
system of first order ODEs with prescribed initial conditions:

       d y(t)[i]
       ---------  = f(t,y(t))[i],
        d t

       y(t=0)[i] = y0[i],

where i = 0, ..., len(y0) - 1

Provides:
  ode  - a generic interface class to numeric integrators. It has the
         following methods:
           integrator = ode(f,jac=None)
           integrator = integrator.set_integrator(name,**params)
           integrator = integrator.set_initial_value(y0,t0=0.0)
           integrator = integrator.set_f_params(*args)
           integrator = integrator.set_jac_params(*args)
           y1 = integrator.integrate(t1,step=0,relax=0)
           flag = integrator.successful()

Supported integrators:
  vode - Variable-coefficient Ordinary Differential Equation solver,
         with fixed-leading-coefficient implementation.
         It provides implicit Adams method (for non-stiff problems)
         and a method based on backward differentiation formulas (BDF)
         (for stiff problems).

         This integrator accepts the following parameters in
         set_integrator() method of the ode class:
           atol=float|seq
           rtol=float|seq
           lband=None|int
           rband=None|int
           method='adams'|'bdf'
           with_jacobian=0|1
           nsteps = int
           (first|min|max)_step = float
           order = int        # <=12 for adams, <=5 for bdf
