[SciPy-user] integrating a system of differential equations
Wed May 27 09:16:53 CDT 2009
If you're having stability problems, usually going to an implicit
integration scheme will help. Looks like the scipy.integrate.ode
class lets you choose an integration scheme based on backward
difference formulas, which should be unconditionally stable. You'll
just need to supply a system function and a Jacobian function.
Hope that helps.
