This is the code and data that reproduces the numerical results presented in https://arxiv.org/abs/2107.01948 The title of the paper might have been changed during revision. This code implements the algorithm based on trajectory matrix. 1, To reproduce the Lorenz experiments, first run get_data_L63.py . Then change the value of variable exp in main_L63.py : exp = 'L63' or 'L63_S1' 2, To reproduce the SSH results, simply run main_SSH.py
