.pad_tt_rank
- pad_tt_rank(factor_list, n_padding=1, pad_boundaries=False)[source]
Pads the factors of a Tensor-Train so as to increase its rank without changing its reconstruction
The tensor-train (ring) will be padded with 0s to increase its rank only but not the underlying tensor it represents.
- Parameters:
- factor_listtensor list
- n_paddingint, default is 1
how much to increase the rank (bond dimension) by
- pad_boundariesbool, default is False
if True, also pad the boundaries (useful for a tensor-ring) should be False for a tensor-train to keep the boundary rank to be 1
- Returns:
- padded_factor_list
