Detailed Description

Stores at state comprised of values and higher-order derivatives.

This state can represent a motion state with position, velocity and accelerations, but also a force-profiles with forces, force-derivatives etc.

Constructor & Destructor Documentation

towr::State::State	(	int	dim,
		int	n_derivatives
	)		[explicit]

Constructs a state object.

Parameters:

dim	The number of dimensions this state has (e.g. x,y,z).
n_derivatives	The number of derivatives. In control a state is usually made up of two (positions and velocities.
