StateSpace.Plot.step(ss); or StateSpace.Plot.step( ss, dt, tSpan, x0, defaultDiagram=Modelica_LinearSystems2.Internal.DefaultDiagramTimeResponse(), device=Modelica_LinearSystems2.Utilities.Plot.Records.Device())
This function plots the step responses of a state space system for each system corresponding to the transition matrix. It is based on timeResponse.
