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 .

WebWe will note that the norm of a vector is sometimes denoted with single bars, that is $\mid \vec{u} \mid$ is a notation commonly used to denote what we have defined. We will not use this notation to prevent confusion with mistaking the norm of a vector and the absolute value of a scalar. Example 1. Calculate the norm of the vector $\vec{u} = (3 ...
The Schatten p-norms arise when applying the p-norm to the vector of singular values of a matrix. If the singular values of the matrix are denoted by σi, then the Schatten p-norm is defined by These norms again share the notation with the induced and entry-wise p-norms, but they are different. All Schatten norms are sub-multiplicative. They are also unitarily invariant, which means that for … WebDefinition 4.3. A matrix norm on the space of square n×n matrices in M n(K), with K = R or K = C, is a norm on the vector space M n(K)withtheadditional property that AB≤AB, for all A,B ∈ M n(K). Since I2 = I,fromI = I2 ≤I2,wegetI≥1, for every matrix norm.
