android - How to get a reference to the last backstack popped fragment? -

-

i add, show , hide fragments. each time add/show fragment, hide previous fragment , add transaction backstack.

when user presses button, fragment popped , i have reference it.

why need reference? hide when user continues next fragment.

so, how reference popped fragment?

edit-25-04-2013:

here's code explain how add new fragment, while hiding previous one. the question how reference last fragment after popped backstack (using button)?

fragmenttransaction fragmenttransaction = getfragmentmanager().begintransaction(); fragmenttransaction.hide(lastfragment); fragmenttransaction.add(newfragment); fragmenttransaction.addtobackstack(null); fragmenttransaction.commit(); lastfragment = newfragment;

i use generated tags each fragment, save tags in stack , persist stack. way hold of every fragment out there - last 1 in specific. see code here.

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
