ScalarViewDenseOutput< T > Class Template Reference

Detailed Description

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

A ScalarDenseOutput class implementation that wraps a DenseOutput class instance and behaves as a view to one of its elements.

Template Parameters

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

#include <drake/systems/analysis/scalar_view_dense_output.h>
