Norm vector

WebCalculating the magnitude of a vector is only the beginning. The magnitude function opens the door to many possibilities, the first of which is normalization. Normalizing refers to the process of making something “standard” or, well, “normal.”. In the case of vectors, let’s assume for the moment that a standard vector has a length of 1. 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 … Ver mais Given a vector space $${\displaystyle X}$$ over a subfield $${\displaystyle F}$$ of the complex numbers $${\displaystyle \mathbb {C} ,}$$ a norm on $${\displaystyle X}$$ is a real-valued function $${\displaystyle p:X\to \mathbb {R} }$$ with … Ver mais For any norm $${\displaystyle p:X\to \mathbb {R} }$$ on a vector space $${\displaystyle X,}$$ the reverse triangle inequality holds: For the $${\displaystyle L^{p}}$$ norms, we have Hölder's inequality Every norm is a Ver mais • Bourbaki, Nicolas (1987) [1981].
