Research direction

Start by reading the linked linear algebra functions section of the Array API specification and the existing discussion in this issue. No implementation file, test, or concrete acceptance criteria is named; the work would first require deciding whether LU factorization belongs in the specification and defining its API.

Written by the indexing model from the issue text.

Description

Needs Discussion RFC topic: Linear Algebra

It seems that many libraries that are candidates to implement the Array API namespace already implement the LU factorization (with variations in API and with the notable exception of numpy).

However LU is not part of the list of linear algebra operations of the current state of the SPEC:

Are there any plans to consider it for inclusion?
