Norm notation
Web24 de mar. de 2024 · The norm of a mathematical object is a quantity that in some (possibly abstract) sense describes the length, size, or extent of the object. Norms exist for … WebThis is the Euclidean norm which is used throughout this section to denote the length of a vector. Dividing a vector by its norm results in a unit vector, i.e., a vector of length 1. These vectors are usually denoted. (Eq. 7.1) An exception to this rule is the basis vectors of the coordinate systems that are usually simply denoted .
