dyntrack.tl.FTLE

dyntrack.tl.FTLE(DT, integration_time, delta_t, copy=False)

Generate a scalar FTLE field from vector data.

Parameters

  • DT (DynTrack) – A dyntrack.DynTrack object.

  • integration_time (float) – Overall integration time for sampling the vector field.

  • delta_t (float) – Delta t used during the integration.

  • copy (bool) – Return a copy instead of writing to DT.

Returns

DT – if copy=True it returns or else add fields to DT:

.ftle

FTLE scalar values of the vector field.

Return type

dyntrack.DynTrack
