Hi Eric,
as Elena's mentor, I can try to shed some light on this question.
IRLS, as used in GLM fitting, does require a matrix, but it's always
diagonal. See, for example, https://bwlewis.github.io/GLM/ , section
"Algorithm IRLS". The motivation for this pull request is exactly this

Hi Elena,
Thanks for this intriguing idea. As far as I ever knew IRLS requires a
matrix. Can you provide me with a citation where I can read about this
vector-based approach?
Thanks,
Eric
