[Octave-bug-tracker] [bug #55570] quiver3 gives error for 4-input form of function

[Rik]

Update of bug #55570 (project octave):

                 Release:                  5.0.90 => dev                    
                 Summary: quiver3 gives error for 3 inputs => quiver3 gives
error for 4-input form of function

    _______________________________________________________

Follow-up Comment #6:

Priority 1: Update documentation to refer to the 4-argument input form, and
remove the 3-input form.  Update the text to more accurately describe what is
going on.

Priority 2: Update input validation to handle 4-argument input form.  Test
code which must pass.


z = peaks (25);
surf (z);
hold on;
[u, v, w] = surfnorm (z / 10);
h = quiver3 (z, u, v, w);


Currently this fails with


error: __quiver__: operator +: nonconformant arguments (op1 is 15625x1, op2 is
625x1)
error: called from
    __quiver__ at line 197 column 10
    quiver3 at line 87 column 10


Changed the Release to refer to the development branch.  Although, as a
documentation and bug fix it can be backported to stable.
