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?

When you define your function, the function declaration line should include the names of the variables into which the input arguments will be stored.
When you call your function, specify the exact values on which you want your function to operate.
This is an incorrect way to define the addme function:
function z = addme(2, 3)
z = 2+3;
end
This is a correct way to define the addme function:
function z = addme(x, y)
z = x + y;
end
and this is a correct way to call the addme function.
theOutput = addme(2, 3)
