I see. Sorry for the inaccurate report.

To be clear, this is not a Matlab compatbility bug, updating bug information. The example given in the link you provided works as is in Octave with scalar scaling factors.

Allowing an array scale factor may work without breaking compatibility to the quiver function, but it would probably not work with the expected handle properties that the quiver function returns.

The Matlab does for quiver here [1] and here [2] both confirm that the scale factor is a scalar only.

This is missing functionality.

Being the scale only a scalar rather than an array prevents one from doing things like those reported here:
