Inheritance diagram for iPiano::Iteration:

Public Attributes
float	beta_n
	beta_n of current iterate (within iterations, this is also used to estimate beta_np1).
float	delta_n
	delta_n of current iterate (within iterations, this is also used to estimate delta_np1).
float	gamma_n
	gamma_n of current iterate (within iterations, this is also used to estimate gamma_np1).
Public Attributes inherited from nmiPiano::Iteration
Eigen::MatrixXf	x_n
	Current iterate.
Eigen::MatrixXf	x_nm1
	Last iterate.
Eigen::MatrixXf	Delta_x_n
	Update: x_np1 = x_n + Delta_x_n.
float	Delta_n
	Difference between two iterates.
float	f_x_n
	Smooth objective function at current iterate.
Eigen::MatrixXf	df_x_n
	Derivative of smooth objective at current iterate.
float	g_x_n
float	L_n
	L_n of current iterate (within iterations, this is also used to estimate L_np1 via backtracking).
float	alpha_n
	alpha_n of current iterate (within iterations, this is also used to estimate alpha_np1).
int	n
	Current iteration.
