Moreover, 11·11 stands for either the /2 vector norm llxll = (x, x)112, or for any matrix norm which is consistent with (or subordinate to) the /2 vector norm in the sense that IIAxll < IIAIIIIxll for eachx inRn and A inL(Rn). In particular, the /2 operator norm and the Frobenius norm are consistent with the /2 vector norm. ForThe Frobenius norm requires that we cycle through all matrix entries, add their squares, and then take the square root. This involves an outer loop to traverse the rows and an inner loop that forms the sum of the squares of the entries of a row. % Output: the Frobenius norm ∑ i = 1 m ∑ k = 1 n a ik 2.
