PHP: Best practice regarding "public" visibility in OOP -

-

do add public beside methods , properties inside classes? or leave out?

1. option 1, without public:

<?php class simpleclass {     // property declaration     $var = 'a default value';      // method declaration     function displayvar() {         echo $this->var;     } } ?>

2. option 2, public:

<?php class simpleclass {     // property declaration     public $var = 'a default value';      // method declaration     public function displayvar() {         echo $this->var;     } } ?>

personally think adding public adds little more clarity code, though considered best practice?

best practice pick coding standard , follow (and put info somewhere in code).

i guess psr commonly used in php:

https://github.com/php-fig/fig-standards/tree/master/accepted

and according psr-2:

"visibility must declared on properties."

so second option way go.

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
