Syntax and Use

import psl
# instantiate selected dynamical system model
model = psl.systems['Duffing'](ts=0.01)
# simulate the dynamical system over nsim steps
out = model.simulate(nsim=2000)
# plot time series and phase portrait 
psl.plot.pltOL(Y=out['Y'], X=out['X'])
psl.plot.pltPhase(X=out['Y'])
