Follow-up Comment #3, bug #31098 (project octave):
The implementation of Horner's scheme in polyval is straightforward (see the
attachment). It fixes the difference between ppval and polyval and it is much
faster: on my pc, the evaluation of
polyval(rand(1,100),rand(100))
drops from 0.123 to 0.019.
Maybe I should start a new item.
