T3Frame.allclose
================

.. py:method:: t3toolbox.frame_variations_format.T3Frame.allclose(other, rtol = 1e-09, atol = 0.0)

   .. code-block:: python

      def allclose(self, other: 'T3Frame', rtol: float = 1e-9, atol: float = 0.0) -> NDArray:  # bool array, stack_shape


   ``True`` (per stack element) if ``other`` represents the same base point as ``self`` (gauge-invariant).

   Compares the *represented* base points, not the cores: ``||self.to_t3() - other.to_t3()|| <=
   atol + rtol * ||other.to_t3()||`` in the dense Frobenius norm (via
   :py:meth:`TuckerTensorTrain.norm`, no densification), **per stack element** (reduce with ``.all()``
   for a single verdict). Invariant to the orthogonal/gauge
   representation -- two different orthogonal bases for the same point compare equal.
