Examples of ca.nengo.dynamics.DynamicalSystem

ca.nengo.dynamics.DynamicalSystem

A state-space model of a continuous-time dynamical system. The system can be linear or non-linear, and autonomous or time-varying.

While a DynamicalSystem can be time-varying, it must be immutable. That is, its properties can change over simulation time, but not over run time.
