MATLAB: AudioFeatureExtractor function not found

Question

I am using Matlab 2018b

[audioIn,fs] = audioread("C:\Users\mooma\Desktop\Audio_Speech_Actors_01-24\Actor_01\1.wav");

aFE = audioFeatureExtractor( "SampleRate",fs,"Window",hamming(round(0.03*fs),"periodic"), "OverlapLength",round(0.02*fs),"mfcc",true);

features = extract(aFE,audioIn);

idx = info(aFE);

Whenever I run this code, an error comes as Undefined function or variable 'audioFeatureExtractor'

Can anyone help me with this . I have to submit project next week.

This function is introduced in R2019b.
