.Modelica_LinearSystems2.Internal

Information

Generally, the functions in this package should not be used by the user.

This package contains models, functions and parameters designed to build up other models of higher level within the library. Some of them cannot be used in an arbitrary way and require particular knowledge how to set the options in the parameter menu. Therefore, only advanced users should deal with contained classes.
