You calculate a value for pp1
each time, do nothing with it, then let the next loop iteration overwrite it. To make use of it, either put the test inside the loop:
for ix=1:2
V='.wav';
ie=num2str(ix);
Stc=strcat(ie,V);
[x1,fs1]=wavread(Stc);
figure,plot(x1);
title('Test Audio');
[pp1,pf1]=pitchauto(x1,fs1);
if (pp==pp1)
msgbox('Matching', num2str(ix)); % show the index number as msgbox title
else
msgbox('Not Matching', num2str(ix));
end
end
or collect the values of pp1
in an array to test afterwards:
for ix=1:2
V='.wav';
ie=num2str(ix);
Stc=strcat(ie,V);
[x1,fs1]=wavread(Stc);
figure,plot(x1);
title('Test Audio');
[pp1(ix),pf1]=pitchauto(x1,fs1); % assuming pitchauto returns a scalar
end
matchidx = (pp == pp1);
if any(matchidx)
msgbox(strcat('Matching indices: ', num2str(find(matchidx))));
else
msgbox('Not Matching');
end
If the values aren't scalar, then this approach is a bit more difficult - you could still use a matrix to collect equal-sized vectors, or a cell array to collect anything - but it's probably easier to stick with the first approach in that case.
