PHP variable with multiple strings to an array -

-

this code in drupal view table template $row = content get..

var_dump($row);  // output: array(5) {      ["field_datum"]=> string(0) ""      ["field_werf"]=> string(9) "comis cui"      ["field_machine"]=> string(17) "graafmachien d293"      ["field_aantal_uren"]=> string(1) "5"      ["view_node"]=> string(50) "bekijk"  }  $uren = $row['field_aantal_uren']; var_dump($uren);  // output: string(1) "5" string(1) "7" string(1) "1"

i've tried explode, str_replace, preg_replace 3 strings in array can loop on them them , make sum. can't make work..

any suggestions transform variable array?

you var_dumping within loop. try this:

$uren[] = $row['field_aantal_uren'];

and outside of loop, have array.

echo array_sum($uren);

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
