I am using Matlab R2008a and I type this code:*
>> %mencari nilai PSD dari data suara Odontoceti (Spinner - 2.wav)
[y,fs]=wavread('Spinner - 2.wav');
[pyy,f]=PSD(xy,256,fs,hamming(256),128,'none');
ys = 10*log10(pyy);
figure(1)
plot (f,ys,'k.-')
grid no
xlabel ('Frekuensi (Hz)')
ylabel ('PSD (dB/Hz)')
title ('Spinner 2')
but i got an error code like this:
??? Undefined function or variable 'xy'.

After
[y,fs]=wavread('Spinner - 2.wav');
Add
xy = y(:, 1);

I've do it but I got another error code:
??? Error using ==> wavread at 67
Cannot open file.
and the number 67 is
error('wavread:InvalidFile', msg);
