I have a question out there for people who use Matlab 4.0a
(I am running it on a sun sparc workstation)
How do you get the sounds to work? I am only to get niose
when I tried using it.  Has anyone used it? 
Can someone post a little blirb on the basics of using it.
Thanks..

Cory

Well, we just got matlab4.0 here and I played with the sound
capability a bit (I "sonified" some of my data, much to my colleagues
shock).  Just generate a long vector and play it.  On Sparcs the
vector is sampled at something like 8192 Hz, that is, a vector of
length 8192 will play for one second. 

Try 

t = 1:8192;
f = 440;
x = sin(2*pi*f*t/8192);
sound(x);

or 

x = sin(2*pi*t.*t/8192);
sound(x);

Good Luck,
