Jordan canonical form

John,

I recall a long time ago implementing a transform for Jordan form for a class 
at Marquette.  It was challenging for me at the time, of course, having not 
done anything like that before.  It was kind of tricky with (from what I'm 
remembering) manipulations along rows and some type of swapping of 
elements...not sure really, it's been such a long time now.  I may have done 
something unique in addition to what the paper had described.  The algorithm 
seemed efficient, but what did I know back then?

I do remember the Journal (Franklin Institute) and the author (Chi Tsong Chen). 
 An Internet search brought it right up:

Unfortunately, it was the days when the PC was just catching on and I had no 
means of keeping an electronic copy from a main frame.
