iphone - Simulate cursor and click -

-

i want simulate mouse pointer , click event on object in view. until able simulate mouse pointer i.e. mouse pointer moves dragging on view. want fire tap event on underlying object on simulated mouse pointer clicked. suppose button. concept finger mouse.

i got you,

1) add uitapgesturerecognizer mouse pointer.

2) in tapgesture handle method,

get finger point,

cgpoint fingerlocation = [tap locationinview:self.view];

make fingerrect this,

cgrect finderrect = cgrectmake(location.x - 5, location.y - 5, 10, 10);

iterate through uiviews in self.view

  (uiview *view in self.view.subviews) {     cgrect frameoftheview = view.frame;      if(cgrectintersectsrect(frameoftheview, finderrect)){         nslog(@"clicked on view %@", view);         return;     }  }

finally method this,

-(void) handletap:(uitapgesturerecognizer *) tap{      //get tapped point     cgpoint location = [tap locationinview:self.view];     cgrect finderrect = cgrectmake(location.x - 5, location.y - 5, 10, 10);      (uiview *view in self.view.subviews) {         cgrect frameoftheview = view.frame;          if(cgrectintersectsrect(frameoftheview, finderrect)){             nslog(@"clicked on view %@", view);             return;         }      }  }

that way can detect touched view, depending on view can call methods want.

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...
