Study the Matlab documentation for the functions repmat()
and reshape() and you will be able to solve this and many
other problems.

Actually, your question seems to be about applying one window to
multiple data (sub)segments. Take a look at spectrogram.m to see if it
is an example of what you are suggesting.

I have a question about windowing in MATLAB. So I have a 1 second signal,
y1 to which I would like to apply a 24ms hamming window. Within the
windowed signal, I want to perform a series of calculations . From what I
understand about windows you can simply multiply y1 and the window function
to get the windowed signal. 
I'm curious though is it possible to split that 1 sec signal into many
(approx 42) windows and perform the computation within those windows? if so
how do I do it in matlab? Basically I want to have the window move from a
24ms segment to another 24ms segment for the entire signal duration.
