quatnormalize - Normalize quaternion

Syntax

n = quatnormalize(q)

Description

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

Examples

Normalize q = [1 0 1 0]:

normal = quatnormalize([1 0 1 0])


normal =

    0.7071         0    0.7071         0
