home view 

ext.define('ext4example.view.login.homepage' ,{ extend: 'ext.container.viewport',  alias : 'widget.home',  requires: [            'ext4example.view.login.westmenu',            'ext4example.view.login.centerpanel'         ],        layout: {            type: 'border',            padding: '0 5 5 5'        },  initcomponent: function() {   this.items= [      {      xtype: 'westmenu',     region: 'west' },{      xtype: 'portletpanel',     region: 'center', } ],      this.callparent(arguments); } });

my controller

ext.define('ext4example.controller.login', { extend: 'ext.app.controller',  stores: ['login'],  models: ['login'],  views: ['login.loginform','login.homepage','login.centerpanel','login.westmenu'],   init: function() {       this.control({         'login button[action=add]': {            },          'login button[action=reset]': {               'click' : function(button, event, opt) {                    var form = button.up('form');                 form.getform().reset();             }           },          'login button[action=connect]': {                'click' :this.connect         }     });  },  connect:function(button,record)  {  var view1 = ext.widget('home');   }

when click on button connect see 2 views on same page want login view desappear , want show home view.

any 1 have solution ?

try:

var win = button.up('login'); win.close();

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
