t3toolbox

T3Toolbox: Tucker tensor trains (T3) – a Tucker decomposition whose central core is stored as a tensor train.

This package root re-exports the frontend surface: the tensor classes (ragged and uniform), the frame/variations/tangent classes, the geometry singletons, the Gauss-Newton fitting models, and the optimizers. Backend users import submodules explicitly (e.g. from t3toolbox.backend import probing) – the backend is namespaced by module and deliberately not re-exported here. Naming conventions: docs/naming_conventions.md.
