classdef(Abstract) AbstractDynamics < handle
    %ABSTRACTDYNAMICS Abstract class intended as superclass for all
    %implementations of dynamic systems.
    %   This abstract class defines the interface that dynamic system
    %   objects should adhere to. As the overall simulation is performed in
    %   discrete timesteps, the dynamics are also evaluated in steps, even
    %   if the underlying system is formulated in continuous-time.
