Line 19:
:I apologize for the edit summary suggesting that the rational normal form in the example was not the one over '''C''', since I imagined that when the minimal/characteristic polynomial does factor over the base field, then the rational normal form would reflect this, which is apparently not the case. Apparently what I was thinking of is called the [[primary rational canonical form]], at least that is what [[modules over a principal ideal ___domain]] says. It would be useful to make this distinction clear, by saying for instance that if the characteristic polynomial is split with simple roots, then the rational normal form is just the companion matrix for the characteristic polynomial, and ''not'' the diagonal form. Also the primary rational canonical form should be mentioned in this article, so that the redlink in the modules.. article can be resolved.

== Turner binormal projective anyone? ==
I've seen quite a bit of literature on this subject, but never seen the (unexplained) term "Turner binormal projective form" used anywhere that is not obviously copied from Wikipedia (and also "rational canonical form" is both more frequent and more informative than "Frobenius normal form", but I'll leave that for the moment). Since the use is unsourced (as are the others, but these at least are easy to back up by independent sources on the internet) it is not the task of WP to push new terminology, I'll boldly '''remove''' the term for now. If any authoritative source of the use of this term can be found, please feel free to put it back, with a source reference.
