Orthogonality
Hi. I removed your addition to Orthogonality since you inserted it between the section with the definition of orthogonal vectors and the section on examples of orthogonal vectors. Well, I think it was not right that way, it interrupted the flow of thought.

I doubt that text is that useful there to start with. While orthogonal matrices are surely important, I don't think they are as fundamental as orthogonal vectors, and orthogonality is a general purpose article. If you look in the see also section of that article, you will see that orthogonal matrices are mentioned there, which should be enough I think.

And a style note. On Wikipedia one should not use upper case in section headings, so one should write write

== Orthogonal matrices ==

instead of

== Orthogonal Matrices ==

You can reply on this page, under this text, if you have comments. Cheers, Oleg Alexandrov (talk) 04:38, 16 January 2007 (UTC)


 * Yeah I wasn't sure what kind of depth the page was aiming for. I thought that it was natural to expand the characterization of orthogonal from vectors to matrices, as it also had a bearing on the mention of linear transformations. Doesn't the section on orthogonal functions also come between the section on orthogonal vectors and the examples?


 * I will take note of the heading issue. Nappyrash 05:09, 16 January 2007 (UTC)


 * You are right about orthogonal functions staying a bit in the way. But orhogonal functions are a natural extension of orthogonal vectors (a function is a vector with an infinite number of components). And then the examples below cover both orthogonal vectors and orthogonal functions. So in a sense those sections kind of belong together.


 * One more note. If you look carefully at this edit and this edit (towards the bottom) you will see that some characters are disappearing, like "==" and "]]". I don't know why, but it is good if you check the "Show changes" button before submitting something to make sure you don't delete things by accident.
