<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.
