previous title: groovy shell settings/config file location on windows , example where can find/create groovysh/groovy shell settings/config file in microsoft windows 7? groovysh has issue groovy-6453 keys don't work correctly on windows version of groovy. i'd used autohotkey remap keys i've started use conemu , haven't figured out how differentiate tabs far autohotkey. i'm hoping i'll able remap keys in config file works globally user , not need autohotkey script anymore. just clarify there nothing wrong conemu specific version of groovysh i'm using. if set title of cmd window start groovysh title stick , autohotkey can check window title. in conemu commands input box enter -new_console:t:groovy"cmd.exe /c title groovy&&groovysh" t:groovy sets title tab conemu's viewpoint , cmd.exe /c title groovy sets title cmd's viewpoint. additional &&groovysh starts groovy console. autohotkey sees title ...

i using oracle 12c, needed understand, 1) facing issue of several sessions in locked state (librarycache). showing me parallel queries running, have not set parallel clause in ddl of table object. migration indexes created parallel clause create not understand why taking dml also. 2) if assume if case while running dml sqleditor executionplan shows me noting parallel. finally got answer through, http://blog.tanelpoder.com/2007/06/23/a-gotcha-with-parallel-index-builds-parallel-degree-and-query-plans/

i'm new matlab, , working on program deals frequency of human voice based on microphone input. biggest problem running musical notes (what dealing in project) increase in frequency exponentially, 1.059463^x each semitone in musical scale. in program dealing with, need both scale graph detected frequency close note number corresponds scale data can work note numbers in terms of notes , musical cents frequency graph can converted midi data. other option have found has been create library of frequencies recorded frequencies compared to, unnecessarily complicated , time consuming. so, in essence, trying scale data a2, frequency of 110hz, correspond note number 45. there way this? i think want: f = 110; %// frequency in hz n = log10(f/440)/log10(2)*12+69; %// 440 hz (note a4) note 69 note = round(n); cents = round((n-note)*100); examples: f = 110 gives note = 45 cents = 0 f = 345 gives note = 65 cents = -21 in accordance this reference , th...

i using singular value decomposition (svd) applied singular spectrum analysis (ssa) of timeseries. % original time series x1= rand(1,10000); n = length(x1); % windows trajectory matrix l = 600; k=n-l+1; % trajectory matrix/matrix of lagged vectors x = buffer(x1, l, l-1, 'nodelay'); % covariance matrix = x * x' / k; % svd [u, s_temp, ~] = svd(a); % eigenvalues of squared eigenvalues of x s = sqrt(s_temp); d = diag(s); % principal components v = x' * u; = 1 : l v(:, i) = v(:, i) / d(i); end i wanted know if there way have singular components (i.e. columns of v) positive. x > 0 in case (and covariance matrix a) you may looking algorithm such non-negative matrix factorization . this available in statistics toolbox in command nnmf , , there freely available third-party toolbox well.
