Classes

  • Doubling — A solver for the Lyapunov equation using iterative doubling.

source class Doubling(max_iterations: int = 10, convergence_rel_tol: float = 1e-05, convergence_abs_tol: float = 1e-08, reduce_sparsity: bool = True)

Bases : LyapunovSolver

A solver for the Lyapunov equation using iterative doubling.

Initializes the solver.

Parameters

  • max_iterations : int, optional — The maximum number of iterations to perform.

  • convergence_rel_tol : float, optional — The required relative accuracy for convergence.

  • convergence_abs_tol : float, optional — The required absolute accuracy for convergence. Either convergence_rel_tol or convergence_abs_tol must be satisfied.

  • reduce_sparsity : bool, optional — Whether to reduce the sparsity of the system matrix
