css - Twitter Bootstrap layout to "wrap" evenly on viewport resize -

-

i'm attempting create responsive layout using twitter bootstrap. there "grid" of images (100x100) i'd display in rows of 1,2 or 4 wide. i'm using ".row" within ".container-fluid" , span3 contain each item inside rows.

<div class="container-fluid">     <div class="row">              <div class="span3 product"><img src="//placehold.it/100x100"></div>              <div class="span3 product"><img src="//placehold.it/100x100"></div>               <div class="span3 product"><img src="//placehold.it/100x100"></div>              <div class="span3 product"><img src="//placehold.it/100x100"></div>     </div>     <div class="row">              <div class="span3 product clearfix"><img src="//placehold.it/100x100"></div>              <div class="span3 product"><img src="//placehold.it/100x100"></div>               <div class="span3 product"><img src="//placehold.it/100x100"></div>              <div class="span3 product"><img src="//placehold.it/100x100"></div>     </div>  </div>

the problem when browser resized width layout changes unevenly. example, when viewport between 769px , 795px wide rows 3 items, , following row 1 item. i'd rather have "even" rows of 2 or 4 items. see demo on bootply.

is there way bootstrap out of box, or need custom viewport calculations layout?

change class of .row divs .row-fluid.

this make either 4 items shown in row, or 1 if scale down window past point. never thing 3 items in row.

How to calculate SNR of signals in MATLAB? -

-
i've encountered simple, yet fundamental problem on calculating snr: there several signals : s1 = original , pure clean signal without noise. n1 = white gaussian noise going added s1. s2 = s1 + n1 (the noisy signal before performing noise-reduction algorithm) s3 = noise-reduced signal (after performing noise reduction algorithm) n2 = s3 - s1 (the amount of noise after performing noise-reduction algorithm) now want compare snr before , after performing noise-reduction algorithm. which signals should consider snr_before!? s1/n1 or s2/n1 ? which signals should consider snr_after!? s3/n1 or s3/n2 ? which commands or functions should use in matlab in order compute snr_before , snr_after? thanks billion putting time on helping me. what know calculating snr before : snrbeforenoise = mean( signal .^ 2 ) / mean( noise .^ 2 ); and snr after : residual_noise = signal - noise_reduced_signal; snr_after = mean( signal .^ 2 ) / mean( residual_noise .^ 2
