how do i get MATLAB 5 to export a "Figure" to PNG or SVG?

You have solved your problem in the meantime, but for other
times you might try to do a PS/EPS file and then convert it
with Ghostscript.

Where does gnuplot come into the play?
Anyway, here is quite a good reference to this excellent
program:
http://t16web.lanl.gov/Kawano/gnuplot/intro/index-e.html

BTW, my approximation to your original problem with gnuplot:

***************************************
set terminal table
set print "rbj.table"
f(x)=cos(pi*x)
print -4, f(-4)
print -3, f(-3)
print -2, f(-2)
print -1, f(-1)
print  0, f( 0)
print  1, f( 1)
print  2, f( 2)
print  3, f( 3)
print  4, f( 4)
set terminal png
set output "rbj.png"
plot [-4:4] cos(pi*x), \
     cos(pi*x+pi/4)/cos(pi/4), \
     cos(pi*x-pi/3)/cos(-pi/3), \
     "rbj.table" with points pointtype 3 pointsize 2

***************************************

This is admittedly a bit round-about, but it works.
Gnuplot-gurus might improve on that one, I'm sure.

that's what the folk at Wikipedia recommend.  it looks like Octave uses
gnuplot (i've downloaded it) and i think i can figger out Octave.
dunno why anyone buys MATLAB anymore.

bad news.  (maybe it's because it's MATLAB 5 and not 6 or 7.)


*snip*

FYI, scanning our product archives and testing out a few things, it looks 
like exporting to PNG using the -dpng flag was introduced in MATLAB 5.3 
(R11), which shipped in March of 1999.  I was able to export to PNG using 
this version.
