No, not a pdf (as far as I know.)
Just viewmat on a small complex matrix, and NO arrows were shown.
You'll (Ian) know whether a pdf is used in the process!
This was in Jios on my iPad.

Did I understand you right -- you tried outputting a PDF in JQt, and the
PDF contained arrows?

Yes, I tried in jios too, and was going to ask the forum how to get the
arrows, but I then tried it in JQt under Windows on the laptop, where they
did appear, pointing in what appeared to be the correct direction.

Jios 903.1 gives the same result (i.e. colours, but not arrows).
When I get time I'll look into this. But for now I'll just say that jios
uses plot/pd to generate a *pdf* of the viewmat pic, which is what it
displays. Generation of the pdf might possibly be corrupt or incomplete.
Might there be a font full of arrows missing? (Just a guess).

I think Esa is right.
It's explained with some examples in the viewmat lab, pages 8/20-12/20.
It does not seem to work on Android though, just returning a blank
window
(while viewmat on real inputs works perfectly).
On the J Playground, it ddes not work either: it just shows the
magnitude,
but not the arrows. Jios 903.1 gives the same result (i.e. colours, but
not
arrows).

I think it represents the angle (phase, argument) of the complex number
while the color is mapped to the magnitude (absolute value, length).

What is the word for what the arrows mean in viewmat when you are
looking
at complex numbers?
I think that multiplying a number by the arrow's corresponding point
is
going to do some kind of shearing (?) in that direction, but can
someone
help me put this concept into words?
Thanks!
