Quaternion unary minus
Since R2020a
mQuat = -quat
example
mQuat = -quat negates the elements of quat and stores the result in mQuat.

Unary minus negates each part of a the quaternion. Create a 2-by-2 matrix, Q.
Q
Q = quaternion(randn(2),randn(2),randn(2),randn(2))
Q = 2x2 quaternion array 0.53767 + 0.31877i + 3.5784j + 0.7254k -2.2588 - 0.43359i - 1.3499j + 0.71474k 1.8339 - 1.3077i + 2.7694j - 0.063055k 0.86217 + 0.34262i + 3.0349j - 0.20497k
Negate the parts of each quaternion in Q.

quaternion
Input quaternion, specified as a quaternion object, an array of quaternion objects of any dimensionality.
Negated quaternion, returned as a quaternion object or an array of quaternion objects of the same size as quat.
Introduced in R2020a
