TensorTrainCompress
​
TensorTrainCompress
[tt]
gives a tensor train representing the same tensor as
tt
with minimal bond dimensions
​
Details and Options
▪
The following options can be given:
"MaxBondDimension"
Infinity
maximum bond dimension χ at each core
Tolerance
0
truncation threshold
ε
▪
TensorTrainCompress
implements standard TT rounding: the train is right-orthogonalized, then truncated by SVD in a left-to-right sweep. The orthogonal environment makes each local truncation optimal for its bond.
▪
With default options the represented tensor is unchanged and only redundant rank is removed.
