Split suggestion[edit]
I suggest splitting this article into Row space and Column space. I have already posted rough drafts of the two articles, and if no one objects I will change this article to a disambiguation page in a few days. Jim 21:15, 11 September 2007 (UTC)
- If this has been done, should we delete this article?daviddoria (talk) 15:33, 19 September 2008 (UTC)
- User:Jim.belk, this has been undone. It was a pointless split to do, and you didn't provide any justification or reason why the useless split was made in the first place. M∧Ŝc2ħεИτlk 23:16, 16 September 2015 (UTC)
- If I recall correctly, they were separate pages in the past, and the move was made to merge them. You can probably find that discussion somewhere if you dig for it. Incidentally, in the See Also section, the article still has a link to Row Space, which just redirects back here, so I'll remove that. --Yoda of Borg (✉) 19:54, 17 November 2015 (UTC)
mistake in article[edit]
the column space of a m by n matrix is a subspace of R^m, not R^n as suggested by the article. — Preceding unsigned comment added by 14.139.128.12 (talk) 05:41, 26 February 2012 (UTC)
This article needs examples with complex matrices[edit]
This article needs to cover the complex case. In particular, this article would lead one to think the rowspace of a complex matrix is the space of linear combination of its rows, when in actuality it is the linear combination of the columns of . There are cases where they are the same, but they're not the same in general. --Yoda of Borg (✉) 08:10, 18 November 2015 (UTC)
heavily formalized writing style?[edit]
I feel as if the writing in this article is somewhat obtuse to people who aren't already familiar with the concept. 165.154.120.84 (talk) 04:37, 15 March 2016 (UTC)
- The writing is indeed far too obtuse, it is written like a math-book and not like a Wikipedia page intended to inform someone with only somewhat the basics. Seeing as concepts like rank, null-space, range, dimension is part of the introduction to Linear Algebra and matrices. — Preceding unsigned comment added by 192.38.10.2 (talk) 16:22, 10 February 2017 (UTC)
