Hi,
You are asking about the characteristics of ode23, ode45, ode15s, and ode15i in terms of being dissipative or anti-dissipative for conservative ODEs. Dissipative methods result in a gradual loss of energy over time, while anti-dissipative methods introduce energy into the system.
For conservative ODEs, ode23 and ode45 are generally dissipative, and so are ode15s and ode15i. None of these solvers are typically anti-dissipative.
