Here is my function:
function playtone(freq,sf,amplitude,duration)
%Plays a simple tone.
%freq = frequency of tone (in Hz).
%sf = sampling frequency (in Hz).
%amplitude = sound amplitude (dimensionless).
%duration = sound duration (in seconds).
t = 0:1/sf:duration;
sound_vector = amplitude*sin(2*pi*freq*t);
sound(sound_vector,sf)
.

Here are my values:
>> freq = 1000;
>> sf = 10000;
>> amplitude = 1;
>> duration = 10;

It works fine for me. Make sure your speakers are turned on, both on your computer, and on the speakers themselves.

Did you save it as test2.m like I had it? If so, it should run. You must have changed the name of it when you saved it. Please attach your m-file with the paper clip icon.
