norm
<mathematics> A real-valued function modelling the length of a vector.
The norm must be homogeneous and symmetric and fulfil the following condition:
the shortest way to reach a point is to go straight toward it. Every convex
symmetric closed surface surrounding point 0 introduces a norm by means of
Minkowski functional; all vectors that end on the surface have the same norm
then.
The most popular norm is the Euclidean norm.
