Description

Compute row and column p-norms.

Usage

row_norms(x, p = 2)
col_norms(x, p = 2)

Arguments

x	a sparse simple_triplet_matrix, or a dense matrix.
p	a numeric at least one. Using Inf gives the maximum norm.

Value

A vector with the row or column p-norms for the given matrix.

Examples

x <- matrix(1 : 9, 3L)
## Row lengths:
row_norms(x)
## Column maxima:
