At long last, the assaulter checks whether the 2-Norm

When matrixes size become larger, like Lena (256 x 256), the advantage of using 2-norm
instead of SVD to acquire largest singular value becomes much more explicit.
of the ith column of X, which we denote by [[?
2], equipped with the Euclidean 2-norm
x,[infinity]] denote the normalized 2-norms
and infinite-norms of the estimation errors ([P.
Clearly, the computations for this formula are much more complex than those for cos [theta](X, Y), so in the 2-norm
we are much better off sticking with the latter measure.
8 The condition number estimated using the matrix 2-norm
is invariant with respect to orthogonal transformations.
3]VMP) to some existing solvable conic relaxations on the 2-norm

infinity]] norm expresses the maximum of generalized gain of the system transfer function matrix for a class of input signals characterized by their 2-norm
so that, again from the definition of the matrix 2-norm
It is a well-known fact about Krylov space solvers that aiming for the smallest 2-norm
of the residual, that is, applying GMRes without restarts, is not only excessively memory consuming, but is often also not much faster than using alternative methods that are suboptimal.
Here and [parallel] * [parallel] denote, respectively, the Frobenius and the 2-norm
, and [cross product] denotes the Kronecker product.
