Re: stable sorts

[Michael D Godfrey]

Ben,

It is claimed that Matlab at release 2010 switched both
sort and sortrows from NOT stable to stable.  2009
is definitely not stable, so your tests om 2010 will
be very interesting.

It appears that Octave sortrows  claims to be stable based
on sort is stable(!).  So, subject to more checking,
it looks like converting sort to stable would be very useful.
And, the C++ stable sort could be used.  (sort is in
src/interpfcn/data.cc and sortrows is in /m/general/sortrows.m).
