advanced thank

if ios can use uidocumentinteractioncontroller:

nsurl *url = [nsurl fileurlwithpath:pathtoyourfile]; uidocumentinteractioncontroller *diac = [uidocumentinteractioncontroller interactioncontrollerwithurl:url]; nsarray *icons = diac.icons; if ([icons count] > 0) {     // smallest available icon:     uiimage *icon = [icons objectatindex:0]; } else {     // no icon found.     // according documentation, case *should not* occur... }

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...
