@zarkon @jamesj I want to consider this matrix [[-1 0]],[1,0]] ...how do they get this matrix [[-1/sqrt(2), 1/sqrt(2)],[-1/sqrt(2), -1/sqrt(2)]]
I think it is a rotation matrix that I'm suppose to be using...I just don't see it
|dw:1330916304388:dw|
wait i think i see it
oh this is a stupid question lol i got it
|dw:1330916464319:dw|
good. The second matrix is a rotation (anti clockwise) of the plane 5.pi/4.
Yes, the product of those two matrices in your last post is not the original second matrix, obviously.
ok ok...I got it I'm doing a one round of QR-RQ using rotation on a 4 by 4 matrix and I don't know why they decide to use these rotations
but thanks for your help @JamesJ you are totally awesome.
Yay I did it! I get the process but I do not get the point of the process. lol
hm, can't help you there I'm afraid!
It is okay @JamesJ I think knowing the process for now is good. I can always ask what the point is later. I have candidacy exams I'm studying for.
