signal processing - Average of several spectrograms in Matlab -


i have many data segments , can make spectogram of single 1 x:

f = [50:200]; [s,f,t,p] = spectrogram(x,window,fs/2,f,fs)

i want calculate average of spectrograms (one spectrogram per segment). segments same length, assume f , t same average spectrogram.

now calculate average p (of segments) , think result in average spectrogram when plotted with: 

surf(t,f,10*log10(averagep),'edgecolor','none');

is logically correct?

css - Make div keyboard-scrollable in jQuery Mobile? -

from can tell, although jquery-mobile-powered pages can contain divs overflow set scroll or auto, , these divs can scrolled one-screen bar or mouse wheel, cannot scrolled using arrow keys, page-up/page-down, or home/end. instead, official "page" div (with data-role="page") absorbs input. perhaps other divs can't acquire focus, i'm not sure. is there way around this? edit: jsfiddle of simple example: https://jsfiddle.net/qogz0shx/ <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script> <script src="https://ajax.googleapis.com/ajax/libs/jquerymobile/1.4.5/jquery.mobile.min.js"> </script> <link rel="stylesheet" href="https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.css"/> <style> #outer { overflow:scroll; height: 50vh; width: 50vw; } #inner { height: 500vh; width: 500vw; } ...
