function MOS=pesq(CleanSignal, DegradedSignal, rate)
% 1. Put clean and degraded wav files
% 2. build pesq from ITU source code (available on the ITU p.862) and
% generate pesq.exe
% 3. Put the pesq.exe in the current path
% 4. Use it like this exp. :
% MOS=pesq('CleanSignal.wav','DegradedSignal.wav','+8000')
% rate : Must select either +8000 or +16000.
%
[Return,strout]=system(['PESQ ',rate,' ',CleanSignal,' ',DegradedSignal, '']);
c=strfind(strout,'(Raw MOS, MOS-LQO):');
if isempty(c)
disp('Error!!!!!!!!');
MOS='It is not valid';
else
MOS_Raw=str2double(strout(c+23:c+28));
MOS_LQO=str2double(strout(c+29:end-1));
disp(' MOS_Raw MOS_LQO');
disp([MOS_Raw,MOS_LQO]);
MOS(1)=MOS_Raw;
MOS(2)=MOS_LQO;
end
I put the wav file and the rate in first line and i have this error: Error: File: pesq.m Line: 1 Column: 19
Invalid expression. Check for missing multiplication operator, missing or unbalanced delimiters, or other syntax error. To
construct matrices, use brackets instead of parentheses. How I can solve it?
