[audioIn,fs] = audioread('cryrumble.wav');
[f0,idx] = pitch(audioIn,fs);
Plot the audio signal and pitch contour.
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.
