Web4 de out. de 2014 · Well, if you want to find the norm of a vector, all you have to do is uniformly scale the unit ball up until it just barely touches the vector, then that scaling factor is the norm of the vector. This follows from the scaling property of norms. (See Minkowski functional for this statement in more technical wording.) WebIn Euclidean spaces, a vector is a geometrical object that possesses both a magnitude and a direction defined in terms of the dot product. The associated norm is called the two-norm.
