php array and returning a default value? -

-

here code: 

<div class="search-menu">   <div class="btn-group fc">     <a class="btn dropdown-toggle" data-toggle="dropdown" href="#">       <?php         $currencies = explode(',', hana_get_opt('_cc'));         foreach ($currencies $currency) {           if ($currency == get_option('woocommerce_currency')){             echo $currency;             break;           }else{             echo "select currency";             break;           }         }       ?>       <span class="caret"></span>     </a>     <ul class="dropdown-menu currency_switcher">       <?php         foreach ($currencies $currency) {           if ($currency == get_option('woocommerce_currency'))             echo '<li><a href="#" class="reset default" data-currencycode="' . $currency . '">' . $currency . '</a></li>';           else             echo '<li><a href="#" data-currencycode="' . $currency . '">' . $currency . '</a></li>';         }       ?>     </ul>   </div> </div>

which works great returns list of currencies , updates page accordingly, have on question if user has yet set value either select currency or apply first option hana_get_opt('_cc') array default. here html generated code: 

<div class="btn-group fc">                         <a class="btn dropdown-toggle" data-toggle="dropdown" href="#">undefined<span class="caret"></span></a>                         <ul class="dropdown-menu currency_switcher">   <li><a href="#" class="reset default active" data-currencycode="sek">sek</a></li>   <li><a href="#" data-currencycode="eur">eur</a></li>                                                         </ul>                     </div>

i no php coder , appreciate provided chris

based on assumption get_option('woocommerce_currency') return null if no currency selected

<div class="search-menu"> <div class="btn-group fc"> <a class="btn dropdown-toggle" data-toggle="dropdown" href="#">   <?php     $currencies = explode(',', hana_get_opt('_cc'));     $currentcurrency = get_option('woocommerce_currency')     if ($currentcurrency === false) {         echo "select currency";     }     else{         echo $currentcurrency;     }   ?>   <span class="caret"></span> </a> <ul class="dropdown-menu currency_switcher">   <?php     foreach ($currencies $currency) {       if ($currency == $currentcurrency)         echo '<li><a href="#" class="reset default" data-currencycode="' . $currency . '">' . $currency . '</a></li>';       else         echo '<li><a href="#" data-currencycode="' . $currency . '">' . $currency . '</a></li>';     }   ?> </ul>

replace if clause if ( $currentcurrency != null ) whatever applies, if get_option('woocommerce_currency') returns other null if not yet set

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
