Google Apps Spreadsheet open specific sheet based on current date (Month) -

-

i creating spreadsheet in google apps used log client attendance. spreadsheet contains 12 sheets. each sheet represents month of year sheet 1 represents january, sheet 2 represents february etc.

i trying create google apps script using on_open function automatically open relevant sheet based on current date.

for example if current date 18/02/2013 spreadsheet automatically open sheet 2 (february) in focus.

i think correct in using spreadsheetapp.setactivesheet don't know how capture date month google app script.

i assuming script flow bit following?

if date = 18/02/2013 spreadsheetapp.setactivesheet 2

any gratefully received.

to month number, 0 - 11:

var month = (new date()).getmonth();

assuming have { sheet1 .. sheet12 } representing january - december, work:

/**  * selects monthly sheet  */ function onopen() {   var month = (new date()).getmonth();    var ss = spreadsheetapp.getactivespreadsheet();   var sheet = ss.getsheets()[month];   ss.setactivesheet(sheet); };

alternatively, name sheets month, , find appropriate monthly sheet name. allow have other non-monthly sheets in spreadsheet:

/**  * selects monthly sheet  */ function onopen() {   var monthtabs = [ "january", "february", "march", "april", "may", "june",     "july", "august", "september", "october", "november", "december" ];    var month = (new date()).getmonth();   var ss = spreadsheetapp.getactivespreadsheet();   var sheet = ss.getsheetbyname(monthtabs[month]);   ss.setactivesheet(sheet); };

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
