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
quaternion
object | array of quaternion
objects
Quaternion for which to calculate the norm, specified as a quaternion
object or an array of quaternion
objects of any dimensionality.
Output Arguments
N
— Quaternion norm
real scalar | array of real numbers
Quaternion norm, returned as a real scalar or an array of real numbers of
the same size as the quat
argument. Elements of
N
are of the same data type as the underlying data
type of quat
.
Data Types: single
| double
