External links modified[edit]
Hello fellow Wikipedians,
I have just modified one external link on Block matrix pseudoinverse. Please take a moment to review my edit. If you have any questions, or need the bot to ignore the links, or the page altogether, please visit this simple FaQ for additional information. I made the following changes:
- Added archive https://web.archive.org/web/20060414125709/http://www.csit.fsu.edu:80/~burkardt/papers/linear_glossary.html to http://www.csit.fsu.edu/~burkardt/papers/linear_glossary.html
When you have finished reviewing my changes, please set the checked parameter below to true or failed to let others know (documentation at {{Sourcecheck}}).

Moved here from article section Row-wise partitioning in under-determined least squares[edit]
[Comment re. below: According to section "Derivation" above this method of calculating [A, B]+ for m>=n+p. Can it then be used for an underdetermined system where by definition m (size of x and equal to number of variables) > n+p (number of equations)?]— Preceding unsigned comment added by Loraof (talk • contribs) 21:40, 21 Februrary 2018 (UTC)
Reference for overdetermined?=[edit]
I don't think the reference cited covers the overdetermined case? Or am I missing something simple? Billlion (talk) 22:09, 20 November 2018 (UTC)
- Sorry I think it was my misunderstanding, I meant row wise and overdetermined. That is not in this article and I cant find similar results for that in the literature. Billlion (talk) 10:11, 21 November 2018 (UTC)
Merge this stub with Woodbury Matrix Identity[edit]
An entire article from one case-study? Probably should be filed and submerged under Woodbury matrix identity or a similar super-topic in Linear Algebra. — Preceding unsigned comment added by 129.93.68.165 (talk) 19:05, 16 November 2021 (UTC)
