plot or view the result of frame blocking

[Ax's]

Hi all,..
i want to create a speech recognition program that use MFCC. I have a problem to plot the frame blocking result. I use MATLAB. this is the coding i use to frame blocking.

m=100;
n=256;
l = length('waka.wav');
nbFrame = floor(((l - n) / m) + 1);
for i = 1:n
for j = 1:nbFrame
M(i, j) = s(((j - 1) * m) + i);



please help me to plot and view the frame blocking result in MATLAB.
thank you..

use buffer for frame blocking;

k is speech wave; N is frame length and Ov_lap is overlapping

y=buffer(k,N,Ov_lap);
[fr_sz fr_nm]=size(y);
t_vec=(1:length(k))/fs;

plot(t_vec(:,1:fr_sz),y(:,fr_nm));

I have try the coding that you give
I have an error

Error using ==> buffer
Input must be a vector.

Error in ==> FrameBlock at 24
y=buffer(k,N,Ov_lap);


I use k=wavread ('waka.wav');
N=256;
Ov_lap =50;

dear Ax's

your .wav file matrix should be a vector, means a column matrix. see help buffer in matlab for details.

Savor; Best.

dear dashkil,..

I have try, try and try this frame blocking.
Iam newbie in DSP.
in normally what the frame blocking output is?
my frame blocking coding output is a matrix (I think it is a matrix) with 256 column. is it a right output?

i guess it is right; pls post the code.
