ruby on rails - PostgreSQL full-text search: how do i scope it? -

-

mostly based on railscasts screencasts, #341.

i'm trying use postgresql full text search, , works, need scope it. search should go through objects object.state=='saved'.

in screencasts method search defined class method, can't use 'where' because 'where' returns array, , search method class method, error here. tried change way:

def test_search(query)  if query.present?   self.where("title @@ :q or text_for_test @@ :q", q:query)  else   scoped  end  end

to:

@tests=test.where(:state=>'saved') @tests.test_search(params[:query])

but rails throws undefined method error.

what else can scope search? or how fix error of attempt?

use textacular gem gives full-text search postgres.

you can use "basic_search" function given textacular similar how use named scopes.

test.basic_search('sonic').where(:status => 'saved')  test.where(:status => 'saved').basic_search('sonic')

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
