norm: Vector space norm

Description

Each of the considered space structures has an associated norm, which is computed for each element by these functions.

Usage

# S3 method for default
norm(x,…)
# S3 method for acomp
norm(x,…)
# S3 method for rcomp
norm(x,…)
# S3 method for aplus
norm(x,…)
# S3 method for rplus
norm(x,…)
# S3 method for rmult
norm(x,…)
# S3 method for rmult
norm(x,…)

Arguments

x

a dataset or a single vector of some type

…

currently not used, intended to select a different norm rule in the future

Value

The norms of the given vectors. ATTENTON: norm.matrix is a wrapper around base::norm
