Undefined function or variable framing

Hello! I am a beginner of using MATLAB. I make my thesis on signal processing to separate vocal and non-vocal from input wav audio file. When I frame the input signal, frame= framing(input, fs, f_d) there is an error of " Undefined function or variable framing". Can anyone help me please? input=10497966x1 double, fs=44100, fd=0.025. input file has size of 40MB. Do I need to segment the input audio? If so could you tell me please how to do segmentation?

Error in line no 4

[data, fs] = audioread('animal_clinic.wav');   % % read sound 
data = data / abs(max(data));  % normalize data
f_d = 0.025;  % do framing
frames = framing(data, fs, f_d);% it is like 0% overlap with rectangular window

Why do you think such a function exists? Did someone give that function to you? A framing.m file I mean?

@May Thu: you will need to save the file with the name framing.m, somewhere on your MATLAB Search Path (e.g. in the current directory). Try this:

which framing -all

to see if MATLAB can find it. If MATLAB can't find it then you have not saved it using that name, or it is in a directory that is not on the MATLAB Search Path.

Could you post a link to the place you found it?

I'm sorry, I said I got it from matlab Q&A session. My mistake. I got it from http://www.jcbrolabs.org/speech-processing Lesson 4 Framing, windowing and pre-emphasis of speech signal. I'm sorry again.. Could you tell me can I do framing 3 to 4 minutes long audio file? If I can, how can I do? and if not, what steps are needed? Could you or anyone answer me please?

@Stephen Cobeldick, I will try this, thanks.

There is a link to framing.m at the bottom of that page. It leads to https://drive.google.com/file/d/0B3qx_fO_3y2AVGV3bkloUl9oWXc/view

The code appears to do the same thing that buffer() from the Communications Systems Toolbox does.
