quatnorm

Calculate norm of quaternion

Syntax

n = quatnorm(q)

Description

n = quatnorm(q) calculates the norm, n, for a given quaternion, q. Input q is an m-by-4 matrix containing m quaternions. n returns a column vector of m norms. Each element of q must be a real number. Additionally, q has its scalar number as the first column.

Examples

Determine the norm of q = [1 0 0 0]:

norm = quatnorm([1 0 0 0])


norm =

     1
