Hello John, Surely not? For the left nullity the vectors are row vectors on the > left, but the matrix is acting on the right (unless I got out of bed > on the wrong side this norming). >
Yes, I now realise that I read the phrase in a "left-associative way", interpreting "kernel of this matrix acting on the right on row vectors" as being about the _kernel_ acting on row vectors. I was also thinking of the fact that the kernel acts from the left via row operations on the matrix to its right. After re-reading it I see that it makes more sense if you read it right-associatively. (I could be somewhat left-right disoriented having just travelled from the UK to the continent.) Anyway, given that this documentation will be read more closely by people who are less familiar with things like left kernels, I still find it a potentially confusing sentence.
