octave: scripts/plot/draw/quiver3.m annotate

annotate scripts/plot/draw/quiver3.m @ 32062:ada96a467a28

quiver: Improve plotting with non-float numeric inputs (bug #59695) * scripts/plot/draw/private/__quiver__.m: Change firstnonnumeric check to look for char instead of numeric to allow for logical inputs. Recast all inputs up to firstnonnumeric as doubles. Check if firstnonnumeric element is 'off' and if so set scale factor to 0 and increment firstnonnumeric. * scripts/plot/draw/quiver.m: Update docstring to include scaling factor option 'off'. Add BIST for int and logical input types. * scripts/plot/draw/quiver3.m: Update docstring to include scaling factor option 'off'. Add BISTs for too-few inputs. * etc/NEWS.9.md: Appended details of changes to quiver note under General Improvements and noted it also applies to quiver3.
