Module vidal 

Vidal and Inverse tensor train representations

This module provides tensor train representations with explicit singular values:

• VidalTensorTrain: Stores tensors and singular values separately (Vidal canonical form)
• InverseTensorTrain: Stores tensors and inverse singular values for efficient local updates
