WebNorm of a vector. The norm is a function, defined on a vector space, that associates to each vector a measure of its length. In abstract vector spaces, it generalizes the notion of length of a vector in Euclidean spaces. There is a tight connection between norms and inner products, as every inner product can be used to induce a norm on its space.
