How to handle a 204 response in jquery ajax? -

-

as have declared success , error ajax options, response 204, ajax method goes option success leads error.

as per documentation can use, statuscode or complete methods disadvantage here have declare status code 2?? series, 3?? series, 4?? series! these response dynamic , not sure http status code.

so, better way handle http status code in jquery ajax?

the jqxhr objects returned $.ajax() of jquery 1.5 implement promise interface. third argument in done function jqxhr object. object has property http status code of result.

jqxhr.done(function(data, textstatus, jqxhr) {}); alternative construct success callback option, .done() method replaces deprecated jqxhr.success() method. refer deferred.done() implementation details. link

    $.ajax({       url: "http://fiddle.jshell.net/favicon.png",       beforesend: function ( xhr ) {           xhr.overridemimetype("text/plain; charset=x-user-defined");        }     }).done(function ( data, textstatus, jqxhr) {        console.log(jqxhr.status); //handle 204 or other status codes here     });

fiddle http://jsfiddle.net/puleos/fva7x/

assuming want treat non 200 status codes error this:

var p = $.ajax({           url: "http://fiddle.jshell.net/favicon.png",           beforesend: function ( xhr ) {              xhr.overridemimetype("text/plain; charset=x-user-defined");            }         });  p.done(function(data, textstatus, jqxhr) {   if(jqxhr.status !== 200) {      handleerror(jqxhr.status);      return;   }   // normal processing here });  p.fail(function(jqxhr, textstatus) {    handleerror(jqxhr.status);  });

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
