i have this code
M=10; %samples/sec
n=-3:1/M:3;
A=2;
phase=0;
f=1;
x=A * sin(2*pi*f*n + phase);
stem(n,x,'linewidth', 2)
title('Discrete-Time Sine Wave: A sin(2*\pi*f*n + \phi)')
xlabel('Time Index')
ylabel('Signal Amplitude')
axis([n(1) n(end) -A A])
grid

Have you taken the Fourier transform or called pwelch()? Try these helpful tutorial links on Fourier Transforms:

http://cns-alumni.bu.edu/~slehar/fourier/fourier.html
Also look up MATLAB demos and webinars where they talk about spectral analysis and the pwelch() function (in the Signal Processing Toolbox) - they just held one a couple of weeks ago. <http://www.mathworks.com/searchresults
