Talk:Matrix determinant lemma

From Wikipedia, the free encyclopedia

[edit] a couple of questions

Entropeneur, you put an inline cite to the "Matrix Reference Manual" for the name "matrix determinant lemma" but no such name appears there. Do you have a reference for the name you chose for the article?

Also, you cited "Numerical Recipes" later in the text. What is that cite supposed to be for? The section you cited is about the Sherman-Morrison and the Woodbury formula. The subject of this article doesn't appear there, and the sentence you tagged (about using unit vectors?) doesn't appear there either. Lunch 20:44, 18 May 2007 (UTC)

[edit] Response to questions from Lunch

- 'Matrix determinant lemma' name: This name appears here: http://www.ee.ic.ac.uk/hp/staff/dmb/matrix/identity.html It does seem that this name is obscure, Google returns just 5 hits in total for "matrix determinant lemma". I would have no particular objection to changing the title of this article.

- Cite of 'Numerical Recipes in C': I was referring just to the ability of u and v to effect row, column or element updates to the matrix. This is why the reference was inserted mid-sentence. Entropeneur 09:04, 21 May 2007 (UTC)
