In mathematics, a norm is a function from a real or complex vector space to the non-negative real numbers that behaves in certain ways like the distance from the origin: it commutes with scaling, obeys a form of the triangle inequality, and is zero only at the origin. In particular, the Euclidean distance in a Euclidean space is defined by a norm on the associated Euclidean vector space, called the Euclidean norm, the 2-norm, or, sometimes, the magnitude of the vector. This norm c… WebThe norm of a vector v is defined by: \left \ v \right \ = \sqrt {\left \langle v,v \right \rangle} where: \langle v,v \rangle is the inner product of v.
