Hi Kevin,
Thank you for interest in my article. I deleted it not because I do not like it, but because I do not wish to associate with or talk to people like Madmath, KSmrqT and their ilk. Here is what they say about the matrix operations covered here:
I have only looked at the article on matrix addition, but it certainly has all the earmarks by being hijacked. Alterations include non-standard definitions and notation, as well as self-promoting links. --KSmrqT 19:41, 21 July 2006 (UTC)
I think I am responsible for bringing this to peoples attention, but I have "trodden carefully" as a comparative newcomer to WP (but a comparative 'old-comer' to maths!). I have been looking at the things mentioned above for a few days, and have to say that I believe that most of the content of the articles Homogeneity (statistics) and Canonical analysis are mathematical gibberish, and the matrix stuff is probably nonsense (I have seen many examples of such over the last 4 decades, but these examples are quite staggering!). I do not wish to appear to be waging a vendetta against any contributor to WP, but I have to say that I cannot find anything worth keeping in the previously mentioned articles, and feel that trying to rewrite them would best be done by deleting everything and starting from scratch.
