Example 3: Phase Entropy w/ Pioncare Plot¶
Import the x and y components of the Henon system of equations.
from matplotlib.pyplot import figure, plot, axis Data = EH.ExampleData('henon'); fig = figure(facecolor='k') plot(Data[:,0], Data[:,1], 'g.') axis('off')
Calculate the phase entropy of the y-component in bits (logarithm base 2) without normalization using 7 angular partitions and return the second-order difference plot.
Y = Data[:,1]; Phas = EH.PhasEn(Y, K = 7, Norm = False, Logx = 2, Plotx = True) >>> Phas 2.0192821496913216
Calculate the phase entropy of the x-component using 11 angular partitions, a time delay of 2, and return the second-order difference plot.
X = Data[:,0] Phas = EH.PhasEn(X, K = 11, tau = 2, Plotx = True) >>> Phas 0.8395
