CorewiseGeometry.randn
======================

.. py:method:: t3toolbox.manifold.CorewiseGeometry.randn(frame, stack_shape = ())

   .. code-block:: python

      def randn(
              self,
              frame:          bvf.T3Frame,
              stack_shape:    typ.Tuple[int, ...] = (),  # extra tangent stack K
      ) -> T3Tangent:  # raw random tangent at frame (ungauged)


   Random tangent at ``frame``: raw i.i.d. N(0, 1) variation cores (the natural corewise Gaussian).
