How to Convert Least Squares Problems into Independent Equations

[MRLX69]

I think that this is best suited here as it is linear algebra specific... sorry if I'm wrong.

Please look at:

I can do parts a,b and c. But I can't do part d.

I've been trying to turn it into n independent least squares equations. Let me know if this is not the way to go or you have other suggestions...


Many thanks,

M

I may have misunderstood your notation, but I don't think that your part d is true. You may be able to convince yourself of that by considering a matrix A = diag(1, 0.1, 0.01).
