def to_t3(self) -> 't3.TuckerTensorTrain':
The base point this frame represents, as a
TuckerTensorTrain(natural ranks).Reconstructed in right-canonical form (the Tucker factors over the right-orthogonal core-TT). For a consistent frame (e.g. from
t3_orthogonal_representations()) this is the base point and equals the left-canonical reconstruction; for a hand-built inconsistent frame it is specifically this form. No consistency check is performed (verifying it would mean densifying multiple reconstructions – the kind of expensive check the library avoids).- Return type:
