OK, last try, sorry to be annoying:
My original submission doesn't seem to show up properly on this page, but the
email looked OK, so I'll try to put it in here. I can't seem to find a way to
preview the formatted output prior to submission.
To see the issue, use this command:
The horizontal arrows have arrow heads, but not the vertical arrow. Actually
the head is there, but the two lines that make it up are parallel to the body
line. It turns out that the angle between the arrow head lines is
proportional
to the length of the arrow in the x-y plane, so an arrow with length only
along the z-axis appears to have no head.
I have a fix. Replace line 219 in _quiver_.m:
with
