Hi, to me, section 4.4.9.1 in the latest MathML 3 draft (20090604) appears to contradict itself on whether a vector is a row or a column. The last sentence of the first paragraph says: > Where orientation is important, such as for pre or post multiplication by a > matrix a vector is treated as a row vector and its transpose is treated a > column vector. whereas, immediately following that sentence, the first sentence of the second paragraph says: > For purposes of interaction with matrices and matrix multiplication, vectors > are regarded as equivalent to a matrix consisting of a single column, and > the transpose of a vector behaves the same as a matrix consisting of a > single row. (MathML 2 contained only that second sentence, see section 4.4.10.1.) Am I missing something? Kevin KoflerReceived on Sunday, 26 July 2009 19:18:48 GMT
