How can I embedded MFCC functions to my matlab

Hi can I get help to do my diploma project "voice recognition using Matlab" by using MFCC approach but the MFCC function doesn't exist in my Matlab program how I can use this function please help me .

I can't use this function

1. r=mfcc(y,fs) where y= input wave sound
2. c=melcepst(y,fs)
3. [ceps,freqresp,fb,fbrecon,freqrecon]=mfcc(y,fs,nbit)where: ceps=cepstrum coefficients, freqresp=fast fourier transform, fb=converts to Mel-frequency scale, fbrecon=converts to standard frequency scale, freqreon=can be used to resample the data in order to create original spectrogram.
4. [ceps,freqresp,fb,fbrecon,freqrecon] = mfcc(s, samplingRate, frameRate)thank you

MFCC is not supplied by Mathworks. Try the File Exchange, such as http://www.mathworks.com/matlabcentral/fileexchange/23119-mfcc
