utv_precompute_entries_frame_sweep
==================================

.. py:function:: t3toolbox.backend.utv_sampling.utv_precompute_entries_frame_sweep(frame_data, index)

   .. code-block:: python

      def utv_precompute_entries_frame_sweep(
              frame_data,  # UT3Frame .data (orthogonal frame)
              index,       # int array, shape=(d,)+W -- the grid points (no packing; the real block is the prefix)
      ):  # -> uniform entries frame sweep: (masked_frame, index, shape, (xis, mus))


   The all-modes **entries** frame sweep (lean ``(xis, mus)``): mask-once, keep ``index`` (fiber slicing
   needs no packing), share :py:func:`entries.tv_precompute_entries_frame_sweep`.
