measurement_jac
===============

.. currentmodule:: pyarts3.workspace

.. attribute:: Workspace.measurement_jac
   :type: ~pyarts3.arts.Matrix

   The first order partial derivatives of the :attr:`~pyarts3.workspace.Workspace.measurement_vec`.

   This variable represents the matrix

   .. math::
       \mathbf{J} = \frac{\partial \vec{y}} {\partial \vec{x}},

   where :math:`\vec{y}` is the :attr:`~pyarts3.workspace.Workspace.measurement_vec` and :math:`\vec{x}` is the :attr:`~pyarts3.workspace.Workspace.model_state_vec`.
   The size of this variable should thus be the size of :attr:`~pyarts3.workspace.Workspace.measurement_vec` times the size of :attr:`~pyarts3.workspace.Workspace.model_state_vec`.
   Please refer to those variables for more information.
