model_state_vec
===============

.. currentmodule:: pyarts3.workspace

.. attribute:: Workspace.model_state_vec
   :type: ~pyarts3.arts.Vector

   A state vector of the model.

   This represents the :emphasis:`chosen` state of the model.
   In the notation of :attr:`~pyarts3.workspace.Workspace.measurement_vec` and :func:`~pyarts3.workspace.Workspace.OEM`,
   :math:`\vec{x}` is the :attr:`~pyarts3.workspace.Workspace.model_state_vec`.

   To choose the state of the model, you must setup :attr:`~pyarts3.workspace.Workspace.jac_targets` to
   include the state parameters you want to be able to change.
