[audioIn,fs] = audioread('cryrumble.wav');
[f0,idx] = pitch(audioIn,fs);
Plot the audio signal and pitch contour.
subplot(2,1,1)
plot(audioIn)
ylabel('Amplitude')
subplot(2,1,2)
plot(idx,f0)
ylabel('Pitch (Hz)')
xlabel('Sample Number')
The error is like this"featurepitchc
Undefined function or variable 'pitch'.
Error in featurepitchc (line 3)
[f0,idx] = pitch(audioIn,fs);"
how to rectify the error

pitch() is from the Audio System Toolbox, R2018a and later.
The Audio System Toolbox itself was new in R2017b.
