php - How to insert multiple ID's in one linked table? -

-

i want insert de employeeid , knowledgeid in knowledgedetail. creates employee nothing in knowledgedetail. i'm there no code, have tried many things have no idea.
first in addprofile.php make profile , @ least choose yoour knowledge. question if make profile , choose knowledge how de id's in knowledgedetail.

table 1

table 2
knowledge: knowledgeid, knowledge
table 3
knowledgedetail: knowledgedetailid, employeeid knowledgeid

employeeid out employees have relation employeeid out knowledgedetail and
knowledgeid out knowledge have relation knowledgeid out knowledegedetail

here's 1 thing that's wrong code:

$knowledge = mysql_query($sqldetail);                                         if ($add === false){     echo 'knowledge not added'; } else {                    echo "knowledge added"; }

in if statement, should compare $knowledge , not $add. so, should be:

$knowledge = mysql_query($sqldetail);                                         if ($knowledge === false){     echo 'knowledge not added'; } else {                    echo "knowledge added"; }

also, add call mysql_error() every time mysql_query() fails:

echo "mysql error: sql = $sql -- error=".mysql_error()";

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...
