Hi,
I just purchased the matlab r2013a software version. The code below was running without error in the previous version I had (r2011a). But when I run it in the r2013a version I get an error message.
Please help.
function VowelFormants = FormantsExtraction (Vowel, fs)
[Vowel fs]=wavread('SymphonyVowel.wav');
n = round(fs/1000) + 2;
w = hamming(length(Vowel));
Vowel = Vowel.*w;
th = ar(Vowel,n); % auto-regressive model of voice
[b,a] = tfdata(th); % transfer function of vocal tract
[h,w] = freqz(b,a);
end
ERROR MESSAGE: Undefined function 'mrdivide' for input arguments of type 'cell'.
Error in freqz (line 101) [h,w,options] = firfreqz(b/a,options);
Error in FormantsExtraction (line 8) [h,w] = freqz(b,a); % frequency response of vocal tract
How can I fix this problem? Your help is much appreciated. Thank you.
