tt_operations
=============


.. py:module:: t3toolbox.backend.tt_operations

.. autoapi-nested-parse::

   Operations on bare tensor-train chains (the ``tt`` family).

   A "tt chain" is the TT core sequence alone -- no Tucker cores, no masks: ragged (a ``len=d``
   tuple of ``stack_shape+(rLi,ni,rR(i+1))`` arrays) or uniform (one ``(d,)+stack_shape+(r,n,r)``
   supercore). Every public function here is polymorphic over the two (inferred via
   ``is_ndarray``), following the shared-sweep precedent of ``tt_orthogonalization``; the ragged
   name doubles as the polymorphic name, so there is no separate ``utt_`` twin.
