Parameters< T > Class Template Reference

Detailed Description

template<typename T>
class drake::systems::Parameters< T >

Parameters is a container for variables that parameterize a System so that it can represent a family of related models.

Parameters are members of the Context. Parameters are not Inputs because they do not flow from upstream Systems, and they are not State because the System does not define update functions for them. If Parameters are modified, they are modified by application-specific logic, extrinsic to the System framework and to the flow of simulation time.

The Parameters include both vector-valued and abstract-valued elements.

Template Parameters

T	The scalar type, which must be one of the default scalars.
