normalize
Description
normalizes the quaternion.quatNormalized
= normalize(quat
)
Given a quaternion of the form , the normalized quaternion is defined as .
Examples
Normalize Elements of Quaternion Vector
Quaternions can represent rotations when normalized. You can use normalize
to normalize a scalar, elements of a matrix, or elements of a multi-dimensional array of quaternions. Create a column vector of quaternions, then normalize them.
quatArray = quaternion([1,2,3,4; ... 2,3,4,1; ... 3,4,1,2]); quatArrayNormalized = normalize(quatArray)
quatArrayNormalized = 3x1 quaternion array
0.18257 + 0.36515i + 0.54772j + 0.7303k
0.36515 + 0.54772i + 0.7303j + 0.18257k
0.54772 + 0.7303i + 0.18257j + 0.36515k
Input Arguments
quat
— Quaternion to normalize
quaternion
object | array of quaternion
objects
Quaternion to normalize, specified as a quaternion
object or an array of quaternion
objects of any dimensionality.
Output Arguments
quatNormalized
— Normalized quaternion
quaternion
object | array of quaternion
objects
Normalized quaternion, returned as a quaternion
object or
