When I first looked at this problem, my first thought was, what are "i," "j," and "k." But I came to the conclusion that "i," and "j," are just the imaginary units, but I still have no idea what "k" is. Any help is appreciated!
That looks like a, b, c are meant to be quaternions. Note that as far as
MATLAB is concerned, i==j unless you redefine one of them, and that is
not what you want here.
