Wordpress - display 3 related posts regardless of the post type, custom or otherwise -

-

i'm trying display 3 posts below single post view (i have custom post types set want query work on single post pages regardless of post type).

however code below don't related posts displayed. when removed .
'&exclude=' . $current 3 related posts display current post being 1 of them. hence why added 'exclude' don't see why not displaying when add in.

any appreciate. thanks

<?php  $backup = $post;  $current = $post->id; //current page id  global $post; $thispost = get_post_type(); //current custom post $myposts = get_posts('numberposts=3&order=desc&orderby=id&post_type=' . $thispost .   '&exclude=' . $current);  $check = count($myposts);  if ($check > 1 ) { ?> <h1 id="recent">related</h1> <div id="related" class="group">     <ul class="group">     <?php            foreach($myposts $post) :             setup_postdata($post);     ?>         <li>             <a href="<?php the_permalink() ?>" title="<?php the_title() ?>" rel="bookmark">                 <article>                     <h1 class="entry-title"><?php the_title() ?></h1>                     <div class="name-date"><?php the_time('f j, y'); ?></div>                     <div class="theexcerpt"><?php the_excerpt(); ?></div>                 </article>             </a>         </li>      <?php endforeach; ?>     </ul> <?php     $post = $backup;      wp_reset_query(); ?>  </div><!-- #related --> <?php } ?>

instead of using get_posts(), use wp_query

<?php  // might need use wp_reset_query();  // here if have query before 1  global $post;  $current_post_type = get_post_type( $post );  // query arguments $args = array(     'posts_per_page' => 3,     'order' => 'desc',     'orderby' => 'id',     'post_type' => $current_post_type,     'post__not_in' => array( $post->id ) );  // create related query $rel_query = new wp_query( $args );  // check if there related posts if( $rel_query->have_posts() ) :  ?> <h1 id="recent">related</h1> <div id="related" class="group">     <ul class="group"> <?php     // loop     while ( $rel_query->have_posts() ) :         $rel_query->the_post(); ?>         <li>         <a href="<?php the_permalink() ?>" title="<?php the_title() ?>" rel="bookmark">             <article>                 <h1 class="entry-title"><?php the_title() ?></h1>                 <div class="name-date"><?php the_time('f j, y'); ?></div>                 <div class="theexcerpt"><?php the_excerpt(); ?></div>             </article>         </a>         </li> <?php     endwhile; ?>     </ul><!-- .group --> </div><!-- #related --> <?php endif;  // reset query wp_reset_query();  ?>

try out code above , modify own need. modified suit own markup.

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...
