Do you mean something like this?
x = rand(1024,1);
y = buffer(x,256);

Saad Rehman comments to Honglei Chen:
for matlab 2016a version FRAMING is done via BUFFER function. Thumbs up!

To recover the original signal after using buffer, use the (:) operator
buffered_signal = buffer(inputsignal, length_of_buffer);
reconstructed_signal = buffered_signal(:);
This assumes that no padding was needed and that there was no overlap used. If padding was needed then to reconstruct the original you would need to know the length of the original.

i think i also have a similar problem, could you also please help me with this: given a with 7.238 second duration and fs=16000, i need 25 msec per frame and overlaps 10 msec every succesive frame.
