Not clear to me what you mean. Please explain a bit more.
Sorry. My understanding and explanation was not clear enough.
For example, Julia's library rotation.jl has a QuatRotation that represents a unit quaternion. Since your package is 3D rotation oriented, I was wondering if you have such a mechanism.
Use Conjugate[q] if the quaternion is symbolic, otherwise you can also use q^-1
I got it!
Note also that the standard package does not handle symbolic quaternions
Oh,really? I had not considered that some mathematica packages do not support symbolic processing.
There is a description of quaternion on this page, but does it not support symbolic processing?
