Jouni,
thanks for your reply.
I could test that
plot([1,2,3],[1,2,3])
setp(gca(), 'xlim', (3.0,1.0))
works,
but
setp(gca(), 'xlim', reversed(getp(gca(), 'xlim')))
gives me an error :

TypeError: unsupported operand type(s) for -: 'reversed' and 'float'
I guess that the issue is that reversed returns the reversed iterator on
the sequnce, not the reversed sequence itself.
Best,
Johann
