Unfortunately, upon first exposure to a topic I usually need a couple of readings to digest the material. So my comments/questions are probably not very insightful.

1. How would one show that performing conjugation on the axial unit vectors makes Conjugate Directions equivalent to Gaussian Elimination? Is there any geometric intuition here? (p. 26)

2. I think the key to understanding the CG method as presented in this paper is understanding section 7.3 Optimality of the Error Term. Luck has it, though, that I do not yet completely follow the author's discussion.
