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 … These norms treat an matrix as a vector of size , and use one of the familiar vector norms. For example, using the p-norm for vectors, p ≥ 1, we get: This is a different norm from the induced p-norm (see above) and the Schatten p-norm (see below), but the notation is the same. The special case p = 2 is the Frobenius norm, and p = ∞ yields the maximum norm. sick leave for part time workersWebVectors are the building blocks of everything multivariable.
