Calculate Quaternion Norm
Create a scalar quaternion and calculate its norm.
quat = quaternion(1,2,3,4); norm(quat)
ans = 5.4772
The quaternion norm is defined as the square root of the sum of the quaternion parts squared. Calculate the quaternion norm explicitly to verify the result of the norm
function.
[a,b,c,d] = parts(quat); sqrt(a^2+b^2+c^2+d^2)
ans = 5.4772
Input Arguments
quat
— Quaternion
scalar | vector | matrix | multidimensional array
Quaternion for which to calculate the norm, specified as a scalar, vector, matrix, or multidimensional array of quaternions.
Data Types: quaternion
Output Arguments
N
— Quaternion norm
scalar | vector | matrix | multidimensional array
Quaternion norm. If the input quat
is an array, the
output is returned as an array the same size as quat
.
Elements of the array are real numbers with the same data type as the
underlying data type of the quaternion, quat
.
Data Types: single
| double
