javascript - merge / join regular expression results for highlighting -

-

i want join/merge result of regular expression.

for example, string

hello foo bar

the regex result pattern /el/ => el
regex result pattern /llo\sfo => llo fo

if use pipe, result 1 match.
pattern /el|llo\sfo/ result el

my desired result should ello fo
use case highlighting multiple pattern in text.

the regex engine processes string once. after character has been consumed, cannot processed again (lookarounds don't count matter because "just look").

since patterns need "overlap" on example string, never match (in 1 regex). however, global flag g , following input:

"helllo foo bar".match(/el|llo\sfo/g)

so solution use 2 separate regexes purpose.

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...
