Update of bug #53583 (project octave):

                  Status:               Confirmed => Fixed                  
             Open/Closed:                    Open => Closed                 


Follow-up Comment #4:

It wasn't that hard to tweak the zero-bracketing algorithm.  I did that here

Octave is now Matlab-compatible.

octave:2> fzero(@(x) besselj(0, x), pi*11-pi/4)
ans =  33.776
octave:3> fzero(@(x) besselj(0, x), pi*10-pi/4)
ans =  30.635

It is still recommended procedure to call fzero with your own bracketing

Marking as fixed and closing report.
