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 1sec 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.

Yes it is possible to split the signal into multiple windows and then
perform the same operation on each window separately..
One way to do is define a variable, say Window number N...And then use a for
loop with N starting from 1 and going to as many windows as you need.
And within the for loop, select the part of the 1 second window as a
function of the window variable N on which you want to do the operation....
I hope this helps..
