Follow-up Comment #5, bug #56659 (project octave):
@Rik: I was able to find this counterexample
> a = 1.3944669777885017e+01;
> x = linspace (-a,a,11);
> x == -fliplr(x)
ans =
1 1 1 1 1 0 1 1 1 1 1
that is, the middle zero is not exactly zero, which is another nice property
one would like to have for symmetric linspaces.
By the way, with my matlab R2019a NONE of the examples in this bug report are
symmetric. Which version did you check?
