Hello,
For the first question of problem 2, would it be possible to have detailed passage from the second to the third equation please?
Appreciate your time and help.
It should be like this I think ...!
Thank you for your clarification, but there is one part I still do not understand, why does this equality hold?
$$ e_n^T Q \alpha = \alpha^T Q e_n $$
I mean unless Q is symmetric, which does not seem to be since \(Q=YXX^{T}Y\)
Update: okay I just proved that Q is symmetric so it makes sense.
