            HybridTrajectory

Hybrid, parameterized, trajectory class. Mimics API of a non-hybrid Trajectory.

vals must be a sequence of trajectory segments. coords is optional (restricts variables to store).

Instance Methods

[hide private]

__call__(self, t, coords=None, checklevel=None, asGlobalTime=False, asmap=False)
Evaluate a parameterized hybrid trajectory at given independent variable value(s), interpreted as global times if optional asGlobalTime==True (default is False).

__init__(self, name, vals, coordnames=None, modelNames=None, timeInterval=None, modelEventStructs=None, eventTimes=None, events=None, FScompatibleNames=None, FScompatibleNamesInv=None, abseps=None, globalt0=0, checklevel=0, norm=2, timePartitions=None)
x.__init__(...) initializes x; see x.__class__.__doc__ for signature

source code

info(self)

source code

sample(self, coords=None, dt=None, tlo=None, thi=None, doEvents=True, precise=False, asGlobalTime=True)
Uniformly sample the trajectory over range indicated, including any event points specified by optional 'doEvents' argument (default True).

showRegimes(self)

source code

underlyingMesh(self, coords=None, FScompat=True)
Return a dictionary of the underlying independent variables` meshes, where they exist.

call(self, t, coords=None, checklevel=None, asGlobalTime=False, asmap=False)
(Call operator)

source code

Evaluate a parameterized hybrid trajectory at given independent variable value(s), interpreted as global times if optional asGlobalTime==True (default is False).

asmap option allows the trajectory to be called as a map, with t = integer values to return the values at successive hybrid event times. Result includes actual time values (in global time if asGlobalTime==True).

Overrides: Trajectory.__call__

(Constructor)

x.__init__(...) initializes x; see x.__class__.__doc__ for signature

Overrides: object.__init__: (inherited documentation)

info(self)

source code

Overrides: Trajectory.info

sample(self, coords=None, dt=None, tlo=None, thi=None, doEvents=True, precise=False, asGlobalTime=True)

source code

Uniformly sample the trajectory over range indicated,
  including any event points specified by optional 'doEvents'
  argument (default True).
Returns a pointset.

precise=False attempts to use the underlying mesh of the trajectory
  to return a Pointset more quickly. Currently, this can only be used
  for trajectories that have a single segment.

If dt is not given, the underlying time mesh is used, if available.

asGlobalTime is ignored for this class (time is always global for
  this class).

Overrides: Trajectory.sample

underlyingMesh(self, coords=None, FScompat=True)

source code

Return a dictionary of the underlying independent variables` meshes, where they exist. (Dictionary contains references to the meshes, not copies of the meshes.) Always returns data in local time frame.

FScompat option selects whether to use FuncSpec compatible naming for variables (mainly for internal use).

Overrides: Trajectory.underlyingMesh
