problems with create tab - android -

-

i need menu 3 tabs.

i have following android code, works:

        tabhost = gettabhost();          tabspec newactivity = tabhost.newtabspec("a");         intent intent = new intent(this,a.class);         intent.putextra("name", name);         intent.putextra("age", string.valueof(age));          newactivity.setindicator("a", getresources().getdrawable(r.drawable.a))                     .setcontent(intent);          tabhost.addtab(createtab(b.class, home_tab_id, "b", r.drawable.h));          tabhost.addtab(newactivity);          tabhost.addtab(createtab(c, more_tab_id, "c", r.drawable.c));

class b , class c:

import android.app.activity;  public class b extends activity{  }

why middle tab has different color compared first , last tab?

i need 3 tabs same. need middle tab have same color - shape first , third one?

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...
