source of json in Multiselect jQuery -

-

i have multiselect of jquery , want source json. took source code autocomplete combobox works, here not work.

my code:

 $(document).ready(function () {         var warning = $("#message");         $("select").multiselect({             //selectedtext: function (numchecked, numtotal, checkeditems) {             //    return numchecked + ' of ' + numtotal + ' checked';             //},             source: function (request, response) {                 $.getjson('http://' + $("[id$='ip']").val() + "/json/auctocomplete.aspx?city=1&term=" + request.term, function (data) { response(data); });             },             select: function (event, ui) {                 $("#mfr").textcontent = ui.item.id;             },             selectedlist: 5,             header: "choose 5",             click: function (e) {                 if ($(this).multiselect("widget").find("input:checked").length > 5) {                     warning.addclass("error").removeclass("success").html("choose 5");                     return false;                 } else {                     warning.addclass("success").removeclass("error").html("");                 }             }         });     });

i searched, , think there not source property jquery multiselect. take @ http://www.erichynds.com/blog/jquery-ui-multiselect-widget . sure there source property it?

i advice you, first load select json, convert multiselect.

// empty select element: <select></select>  // in javascript: $(document).ready(function () {      var url = 'http://...';       $.getjson(url,function(result){                $.each(result, function(i, field){                       var option = $('<option value="' + field.value + '">' + field.text + '</option>');                       $('select').append(option);                });                 $('select').multiselect({...});      }); });

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
