php - How to update object properties in a AWS S3 Bucket -

-

i've uploaded 25k files (large media files) s3 bucket. used aws sdk2 php (s3client::putobject) perform uploads. now, need update metadata these files i.e change contentdisposition attachment , assign filename.

is there way perform without requiring re-upload file? please help.

yes, can use copyobject method, set copysource parameter equal bucket , key parameters.

example:

// setup $s3 connection, , define bucket , key resource. $s3->copyobject(array(   'bucket' => $bucket,   'copysource' => "$bucket/$key",   'key' => $key,   'metadata' => array(     'extraheader' => 'header value'   ),   'metadatadirective' => 'replace' ));

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
