(OK, saw this file in a backlog of email.  Hans must be sending these through 
manually.)  It is a possibility.  That matrix code is sort of a tacked on thing. 
  But unless we understand what the problem is how can we know that there is 
extraneous, inefficient code?  However, if you believe what you've coded meets 
the definitions and format in the documentation and is faster, then consider 
redoing the patch with the old, unneeded code removed.  Otherwise, it will leave 
cruft floating about, just what you are attempting to improve upon.

Thanks,
