I notice in beginning of the "Notation" section, that the transposed notation and its alternative are exactly the same. Someone who knows the correct notations should edit it. —Preceding unsigned comment added by 75.173.43.85 ( talk) 10:42, 14 May 2010 (UTC)
Are we sure that this (IMO questionable) alternative notation is conventionally used in some context? What context? Please give references. The history page shows that the text about alternative notation was inserted by an anonymous newbie (

I tried too much to find the geometry of determinate adjoint inverse row and column vector but still I'm hopeless please explain it Muzammalsafdar ( talk) 14:33, 15 April 2016 (UTC)
Matrix multiplication is a writing system based on left-to-right reading. An editor mentioned that the use of column vectors as input for matrix transformation may appeal to readers of a right-to-left writing system. Since composed matrix transformations should concur with matrix multiplication, the article argues that row vectors are preferred. Any effort to provide for a right-to-left matrix and vector process would require modification of the fundamental row x column convention. — Rgdboer ( talk) 23:16, 29 March 2018 (UTC)
The section Row and column vectors#Preferred input vectors for matrix transformations violates WP:NPOV by including only carefully chosen references that go against the much more common practice in linear algebra books and elsewhere of having matrices act as functions on the left on column vectors. Of course the right action on row vectors has the advantage that to act by AB one acts first by A and then by B, but that is not the commonly used action of matrices on vectors because it has the major disadvantage of being backwards from the way function composition is standardly written.

The article says: a column vector is a column of entries. Actually, I don't know what a column of entries is. As far as I know, in linear algebra, there is no concept of a column as such. Thr only occurrence is a column in a matrix, being one of the matrices . In my opinion a column vector is formally a matrix, or a n-tuple of n 1-tuples: , or .

@ JayBeeEll: This discussion appears to be about the lead, but I don't think my edits from last year touched that? — MarkH21 talk 22:27, 30 November 2022 (UTC)
See also the discussion above. The concept 'column' doesn't exist in linear algebra, so a definition can't be given with this term. Furthermore: the article matrix (mathematics) says: "Matrices with a single row are called row vectors, and those with a single column are called column vectors."
