Update of bug #46658 (project octave):

                Category:                    None => Octave Function        
              Item Group:                    None => Performance            
                  Status:                    None => Confirmed

Follow-up Comment #1:

Setting TolX with


optimset ("TolX", 2 * eps (class (x)))


works for me.

Matlab definitely documents that the default TolX value is eps("double"),
which is what Octave's fzero is using.
