[Octave-bug-tracker] [bug #55570] quiver3 gives error for 3 inputs

[Mike Miller]

Update of bug #55570 (project octave):

                  Status:                    None => Confirmed              
                 Release:                   5.0.1 => 5.0.90

Follow-up Comment #1:

Confirmed with 5.0.90, and this does not seem to be a regression, just a bug
that is never exercised. All of the help and demo examples for quiver3 use the
6-argument form.

This error occurs with both the 3-argument form, when passing in x,y,z as
vectors, or as a meshgrid.
