lagrangian.MapOfFiniteLyapunovExponents

class lagrangian.MapOfFiniteLyapunovExponents

Bases: pybind11_builtins.pybind11_object

Handles a map of Finite Size or Time Lyapunov Exponents

__init__(self: lagrangian.core.MapOfFiniteLyapunovExponents, map_properties: lagrangian.core.MapProperties, fle: lagrangian.core.FiniteLyapunovExponentsIntegration, stencil: lagrangian.core.Stencil = Stencil.TRIPLET, reader: lagrangian.core.Reader = None) → None

Default constructor

Parameters

  • map_properties (lagrangian.MapProperties) – Properties of the regular grid to create

  • fle (lagrangian.FiniteLyapunovExponents) – FLE handler

  • stencil (lagrangian.Stencil) – Type of stencil used for the calculation of finite difference.

  • reader (lagrangian.reader.NetCDF) – NetCDF used to locate the hidden values​​ (eg continents). These cells identified will not be taken into account during the calculation process, in order to accelerate it. If this parameter is not defined, all cells will be processed in the calculation step.
