How can i determine the amplitude, phase, period, sampling frequency, circular frequency (Hz), and angular frequency (rad/sec) of the sine wave

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])

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

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

oh i didn't take it yet. just a basic one

but, thank you anyway. i'll try look up the links first
