comment Is the QR algorithm for computing eigenvalues efficient for today's standards?
Thanks for the answer.. The additional information is very interesting too.

comment Is the QR algorithm for computing eigenvalues efficient for today's standards?
I'm sure it is implemented in matlab and other mathematical software if you call it explicitly but the point of my question wasn't exactly that.. Is it efficient for today's standards? Would it be used by software like matlab by default or is it considered kind of obsolete?

Thanks. I guess they still have a typo for including 0 in their sum, though..

comment Using Lagrange's Interpolation Formula to show that boolean functions over finite fields are polynomials
Thanks you. What you say makes sense.. In fact, in a different part of this book they justify something very similar to the equation that you mentioned. There is one issue that still worries me. It seems to me that the text has a typo: $k$ should start from $1$ instead of $0$ as you stated (or end in $2^n-2$ instead of $2^n-1$). The problem is that they use the formula with $k$ starting from $0$ in order to do other things.. Can you confirm that it is a typo and your version ($k$ starts from $1$) is correct? So far I have been confirming that but maybe I'm wrong..

comment Row reduction over any field?
You're right, I now realize that the question was confused on the first place! Apparently I'm quite confused myself! I will look into it and I'll correct the question soon. Thanks
