Comment:
KDC,
OK, see if you can shoot a hole or two in this one. ;-) Ring is still
optional, but rows/columns, and scale factor ''must'' be given by
keywords. Column operations are implemented by building the equivalent
row operation version and then transposing it.
Docstring leans towards rows, but I think there is enough info on the
column variants. Two small reminders about 0-based indexing. New doctest
showing dense implementation as default, but now has sparse keyword added.
Thanks for the help with this one.
Rob
