vec_len: Calculate Vector Length
In bbuchsbaum/fmrireg: R package for the anlysis of fmri data
vec_len R Documentation
Calculate Vector Length
Description
Computes the Euclidean (L2) norm of a vector or the norm across a specified axis of a matrix.
Usage
vec_len(vec, axis = 1)
Arguments
vec
A numeric vector or matrix.
axis
An integer specifying the axis to compute the norm across.
1 for columns and 2 for rows. Default is 1.
Value
A numeric vector containing the Euclidean norms.
Examples
vec <- c(3, 4)
vec_len(vec) # Should return 5
mat <- matrix(1:6, nrow = 2, ncol = 3)
vec_len(mat, axis = 1) # Norms of rows
vec_len(mat, axis = 2) # Norms of columns
