Calculate conjugate of quaternion
n = quatconj(q)
n = quatconj(q)
calculates the conjugate,
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 conjugates. Each element of
q
must be a real number.
Aerospace Toolbox uses quaternions that are defined using the scalar-first convention.
The quaternion has the form of
The quaternion conjugate has the form of
Determine the conjugate of q = [1 0 1 0]
:
conj = quatconj([1 0 1 0]) conj = 1 0 -1 0
