Update of bug #48889 (project octave):

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


Follow-up Comment #7:

This was far trickier than I expected.  There is a questionable choice in the
algorithm used by Matlab for rose which means that the first and last bins may
not be centered on the values specified by the user.  I added a Programming
Note to the documentation, and also a warning() if the situation is
encountered.  Matlab itself is now trying to deprecate rose in favor of
polarhistogram which does not have this issue.

See cset http://hg.savannah.gnu.org/hgweb/octave/rev/e9f77d099a63.

Fixed, closing report.
