2016年3月18日 · The correct thing is $\;b-a\;$ for the direction vector $\;\vec{ab}\;$. The substraction $\;a-b\;$ gives the opposite direction vector, namely $\;\vec {ba}\;$
Matrix multiplication - Express a column as a linear combination
The 3 3 rd column of AB A B, as you've written it, looks like a 3 × 3 3 × 3 matrix, not a 3 × 1 3 × 1 matrix (i.e. a column vector). Not quite: we need to add entries. So the third column of matrix …
For real column vectors a and b, ab = aTb = b a 1 a 2 a 3 0 B B B @ b 1 2 b 3... 1 C C C A = a 1b 1 + a 2b 2 + a 3b 3 + (1) or, written in a more compact notation ab = X i a ib i; (2) where the …
Notice the meaning of (AB)C = A(BC) when C is just a column vector x. If that vector x has a single 1 in component j, then the associative law is (AB)x = A(Bx). This tells us how to multiply …
