.. py:method:: t3toolbox.fitting.UniformGaussNewtonModel.gradient()

   .. code-block:: python

      def gradient(self) -> ut3m.UT3Tangent:  # g = Π 𝒥ᵀ r (+ g_R), a UT3Tangent at frame


   The gradient ``g = geometry.project(𝒥ᵀ r)`` -- gauged on the manifold, raw on corewise -- plus the
   regularizer gradient ``g_R`` when set.
