The spectral norm, or ||A||2 is sometimes refered to as 'the' matrix norm.
Wolfram solved the problem for me.
Hi, I'm looking over noted from a lecture about matrix norms. I have had a look on the internet and there seems to be various different types of matrix norms, 1-norm 2-norm infinity-norm etc.
If in the lecture it is the first time I have heard about norms and the lecturer didn't say which sort of norm it was, what type of norm is he most likely to be teaching us about?
An example question would be, Find the norm of matrix B, where B is a 2x2 matrix. What sort of norm would he most likely be looking for?
