This is untested, but it should give you an ideal of what to do.

Code:
sigdata = your original signal in a row vector
spf = 160; % number of samples required per frame
sigdata_pad = [sigdata zeros(1,spf-mod(length(sigdata),spf)]; % pad the signal with zeros so that its length is a multiple of 160
framed_data = reshape(sigdata,[],spf);M

I have tried the above code but there is some error, how to get rid of the error?
??? Error using ==> reshape
Product of known dimensions, 160, not divisible into total number of elements, 11412.
Error in ==> C:\MATLAB6p5\work\test.m
On line 16 ==> framed_data = reshape(sigdata,[],spf);

I have sloved the problem by changing it to
framed_data = reshape(data_pad,[],spf);
is that right?
also how to plot a graph of it?
I have tried before, but the graph look very strange
so is it possible to represent the framed_data in a waveform/ line graph?
