angularjs - What is the best practice to pass parameters from Controller to a directive? -

-

i'm new in angularjs

in angular app, have directive , controller. need controller send options of kinds of configurations, including callback methods.

my directive element implements 1 button post data webservice. desire controller send url "post" method , send callback method, have called after "post" in directive.

how best way this? practice send callback methods this?

i specify parameters in tags of element. instance:

<my-directive my-service="someservice" my-callback="somecallback" />

inside directive use $parse function read/set these values:

var getservice = $parse(attrs.myservice),     setservice = getservice.assign,     service = getservice(scope);

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
