I recorded a .wav file using simulink blockes: from audio device->to audio devcie(-> to audio file).

I was trying to use msspectrum to showing the averaged PSD spectrum. So I wrote this simple program:
[filename,path]=uigetfile('*.wav','c:\Program Files\matlab')
file=fullfile(path,filename);
[y,Fs,nbits]=wavread(file);

h2 = spectrum.periodogram('hamming');
hopts = psdopts(h2,y); % Default options based on the signal x
set(hopts,'Fs',Fs,'SpectrumType','onesided','CenterDC',false);
msspectrum(h2,y,hopts)

it turned with the following erros:
??? Error using ==> times
Matrix dimensions must agree.

Error in ==> computeperiodogram at 55
xw = x.*win;

Error in ==> periodogram at 116
[Sxx,w] =
computeperiodogram(x,win,nfft,esttype,Fs);

Error in ==>
spectrum.periodogram.thismsspectrum at 16
[Sxx W] = periodogram(x,...

Error in ==> spectrum.periodogram.msspectrum
at 16
[Sxx W] = thismsspectrum(this,x,opts);

Error in ==> Untitled2 at 11
msspectrum(h2,y,hopts)

Anyone has any idea what was the problem?
