Talk:Row echelon form

From Wikipedia, the free encyclopedia

My Precalculus book reports that Row-Echelon form contains the requirement:

"A matrix in row-echelon form has the following properties ... 2. For each row that does not consist entirely of zeros, the first nonzero entry is 1 (Called a leading 1) ..." - PRECALCULUS 7th Edition, Larson & Hostetler

Which is contrary to what is reported in the article.

Apparently, there isn't universal agreement about this. Some books include that requirement and others don't. A book I have also says this, but someone else here has a book that doesn't say it. See Talk:Gaussian elimination#REF and RREF requirements. Eric119 02:52, 2 December 2006 (UTC)

I added a note; I think that the article should mention that there are two slightly differing definitions. -- Jitse Niesen (talk) 13:52, 2 December 2006 (UTC)
