Why pitch function is not working ?

[audioIn,fs] = audioread('G:\guitar tune\guitartunes\A_String.wav'); [f0,idx] = pitch(audioIn,fs); subplot(2,1,1) plot(audioIn) ylabel('Amplitude')

subplot(2,1,2) plot(idx,f0) ylabel('Pitch (Hz)') xlabel('Sample Number')

This is my code. If i run this, its show like this as output.

Undefined function or variable 'pitch'.

Error in Siva2109 (line 10) [f0,idx] = pitch(audioIn,fs);
