I'm using the Quaternion package:
<< Quaternions`
Very simply, I would like to be able to get the individual components of the quaternions by themselves.
My problem is, if I try
Re[FromQuaternion[Quaternion[1,2,3,4]]]
I get
1+Re[3J+4K]
I would like to isolate the components instead. Then I could get
1
... or 2 or 3 or 4. How can I do this?
ALSO
Is it possible to convert quaternions into a vector?
