t3_conversions

Conversions between a (ragged) Tucker tensor train and other representations (dense tensor, flat vector, plain tensor train, canonical/CP factors).

Functions

t3_to_dense(x[, squash_tails])	Fully contract a Tucker tensor train to create a dense tensor.
t3_to_dense_chain(tucker_cores, tt_cores[, squash_tails])	Chain-contract (Tucker-absorbed) TT cores into a dense tensor -- the representation-agnostic core
t3_to_vector(x)	Converts T3 to a 1D vector containing all of the core entries.
t3_from_vector(x_flat, shape, tucker_ranks, tt_ranks)	Constructs a T3 from a 1D vector containing the core entries
t3_to_tensor_train(x)	Convert TuckerTensorTrain to tensor train by contracting Tucker bases with TT cores.
t3_from_tensor_train(tt_cores)	Convert tensor train into Tucker tensor train by using identity matrices for Tucker bases.
t3_from_canonical(factors)	Constructs Tucker tensor train from Canonical decomposition.
