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

and can go to the menu and "Copy Figure" and paste it into Micro$hit
Word, but i can't find a way to export that to .png or .svg either.
i'm trying to upload some math function graphs into Wikipedia and i
can't, for the life of me, figger out gnuplot.

In Matlab, after plotting the figure, enter in the command window:
print -dpng 'prob3ef.eps'

oooh, oooh, i have to try that.  i'll report how this undocumented
feature works.  i presume it should be  'prob3ef.png' instead of
'prob3ef.eps'.  i did see something like this for eps, but i couldn't
believe this PC with micro$hit office couldn't even deal with
encapsulated postscript.

this missing format crap should have been dealt with more than a decade
ago.

From what I've seen, EPS and MicroSnot Office aren't good friends. MicroSnot
much prefers things like jpegs, bmps, wmf's, etc. EPS requires a (gasp!)
postscript interpreter.

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

??? Error using =3D=3D> print

so MATLAB 5 doesn't speak PNG.  i'm trying to create a simple and
uncluttered drawing of why sampling at precisely twice the highest
frequency of content still ain't good enough (it has to be strictly
higher than twice the highest frequency of content). and i wanna upload
this to Wikipedia and put it in the article on the sampling theorem.

can anybody take the script above and turn it into a .png or .svg
image?  i s'pose even a .gif would do, but they frown on it.

of course teaching a man to fish is better than giving him a fish, but
i'm starving at the moment.

Yeah, must be the version 5. Octave 2.9.5 works, but in the mean
time, eat:

thanks, Randy. but, even when i'm starving, i's still a picky eater.

did Octave do this?   it looks different than ML.  can you make the
cosine curve (the one with the lowest amplitude) blue (that was the
default color for ML plots) and put in little circles instead of little
crosses at the intersections?

doesn't matter.  there is already a drawing there but the guy put in
dozens of different phases, cluttering it up, and it looks to me that
three or four different phases will get the idea across just fine.

Sheesh, Robert! If I didn't love you...

Yup.

Yeah, I didn't notice that the first time. Octave does differ
from Matlab in these types of annoying ways.

mmmm.  num.  hit the spot.

now, Randy, you agree to release all rights to this SOB, right?
because that's the only way i can upload it to Wikimedia Commons.

BTW, Octave is free?  i'm using a PC of recent (we don't need to call
the Weather Service to tell them that hell is freezing over) so, i
s'pose i can download it.  any particular place or do i just google it
to find out?

No, it's mine - ALL MINE ... Mwah ha ha ha ha ha haaaaaaa...........

Yeah. Well, it'll cost you the hard drive space to store it on.

And who said miracles were just for the Apostolic age?

http://www.gnu.org/software/octave/

Hmmm. I took a look at the download page and they have two
Windoze versions: one if you have cygwin installed and one
if you don't. And the one sans cygwin is out-of-date by
quite a few versions. 

Even though it's a pain in the tush, I'd download and install
cygwin first just so you can get the latest version. 

Or, if you're really insane, you could install the Host/Windows
Guest/Linux flavor of VMWare, install a nifty linux distro into the
virtual machine, THEN install the linux version of octave.

Of course the smartest thing to do is completely toss MicroSnot and
install linux (I like Fedora Core 4). I have the Host/Linux
Guest/Windows 2000 version of VMWare installed so I still get the best
of both worlds.
