Talk:Arrowhead matrix

harmonization of notation

Notations in the intro and first section are inconsistent. Should the tip of the arrow be on the top left or bottom right corner? This matters for the computation of the inverse (for example) Best, --Doubleclavier (talk) 22:48, 20 March 2021 (UTC) P.S. my limited English restricts me to intervene

Argh this is confusing. Ideally one would fix the inconsistency, but the problem is that the source uses the bottom right notation, so one would need to look carefully at the indices. Instead I just emphasized what the orientation is. Tercer (talk) 21:24, 6 March 2024 (UTC)
