For a real Hilbert space we have ‖ f ‖ H = f, f H for each f ∈ H. So H can be considered as a normed space endowed with a norm ‖ ⋅ ‖ H. It provides a distance d H on H such that d H ( x, y) = ‖ f − g ‖ H for each f, g ∈ H. http://staff.ustc.edu.cn/~wangzuoq/Courses/20F-SMA/Notes/Lec13.pdf iphone xs screen protector best buy

WebMatrix Norms: It is often desirable to have a notion of the \size" of a matrix, like the norm or magnitude of a vector. One way to manufacture such a thing is simply to regard the n2 entries of a matrix A2M n(R) as the components of a vector in Rn 2 and take its Euclidean norm.
