brainpy.analysis.PhasePlane2D

class brainpy.analysis.PhasePlane2D(model, target_vars, fixed_vars=None, target_pars=None, pars_update=None, resolutions=None, **kwargs)

Phase plane analyzer for 2D dynamical system.

Parameters:

• model (Any) – A model of the population, the integrator function, or a list/tuple of integrator functions.

• target_vars (dict) – The target/dynamical variables.

• fixed_vars (dict) – The fixed variables.

• target_pars (dict, optional) – The parameters which can be dynamical varied.

• pars_update (dict, optional) – The parameters to update.

• resolutions (float, dict) –

__init__(model, target_vars, fixed_vars=None, target_pars=None, pars_update=None, resolutions=None, **kwargs)
