TensorTrainTools Overview
Tensor trains represent high-rank tensors as chains of small cores, turning exponentially large arrays into a compact format that supports decomposition, compression, and arithmetic. The functions fall into a few natural groups: construction, conversion to and from dense arrays, rank control and arithmetic.
Construction
— represent a tensor as a train of rank-3 cores
— create a random tensor train with given dimensions and bond dimensions
Conversion
— decompose a dense array into a tensor train, with controlled truncation
— assemble the dense array represented by a tensor train
Rank Control
— assemble the dense array represented by a tensor train
Arithmetic
