Matrix DUNE::Control::LinearSystem::simLinearSystem	(	const Math::Matrix &	a_u,
		double	threshold
	)

Simulates a linear systems at the current time step considering the current state m_X0 before simulating and updates both m_X0 and m_Y0 respectively with the new state and output.

Parameters

a_u	the control input
threshold	input output difference threshold for conditional state update. Will not update state if difference is larger than threshold

Returns

m_Y0 the output
