tensorly.tt_tensor.tt_to_unfolded

tt_to_unfolded(factors, mode)[source]

Returns the unfolding matrix of a tensor given in TT (or Tensor-Train) format

Reassembles a full tensor from ‘factors’ and returns its unfolding matrix with mode given by ‘mode’

Parameters:	factors: list of 3D-arrays TT factors mode: int unfolding matrix to be computed along this mode
Returns:	2-D array unfolding matrix at mode given by ‘mode’
