html - IE9 Bug ? Mysteriously growing DIV -

-

i have following little sample:

<!doctype html> <html> <head> <meta charset="utf-8" /> <title>test</title> <style type="text/css">     table.sample { width: 600px; table-layout: fixed; }     table.sample col { width: 60px; }     table.sample td { height: 20px; line-height: 20px; padding: 0px; }     table.sample input { width: 55px; height: 17px; padding: 0px; margin: 0px; border-width: 1px; } </style> </head> <body>     <div id="scrolldiv" style="width: 400px; overflow: auto; background-color: #cccccc;">         <table class="sample">             <colgroup><col /><col /><col /><col /><col /><col /><col /><col /><col /><col /></colgroup>             <tr><td>0</td><td>1</td><td>2</td><td>3</td><td>4</td><td>5</td><td>6</td><td>7</td><td>8</td><td>9</td></tr>             <tr><td><input type="text" /></td><td>1</td><td>2</td><td>3</td><td>4</td><td>5</td><td>6</td><td>7</td><td>8</td><td>9</td></tr>             <tr><td>0</td><td>1</td><td>2</td><td>3</td><td>4</td><td>5</td><td>6</td><td>7</td><td>8</td><td>9</td></tr>         </table>     </div> </body> </html>

this works ok on ie8, ie10, chrome, firefox, safari, ... bugs on ie9.

when start typing text box, div grows in height. scrollbar not move, div grows below scrollbar.

i can't define height of div in css number of lines variable , i'm not sure scrollbar present (as number of columns variable in real example).

i can solve problem following javascript code, wondering doing wrong provoke error.

var div = document.getelementbyid('scrolldiv'); div.style.height = div.offsetheight  + "px";

thanks

this appears bug in ie9 how handles overflow-x:auto. adding display:inline-block css div worked great me. source:

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...
