I just opened a pull request to add the higher-order SVD (HOSVD) in scipy.linalg: https://github.com/scipy/scipy/pull/14284

The HOSVD is a technique used for example in the field of tensor networks for higher dimensional structures. It generalizes the idea of the SVD to higher dimensions. The implementation is based on Ref. [1].

Thank you for this contribution. The paper is well cited, so this is a good candidate for inclusion. I had a brief look at the PR: the implementation is fairly straightforward and needs mostly stylistic alterations. I'm glad to see you've already received some feedback from Pamphile.
