I am not sure how to document that in the help message since the value of log10_rejection is hard wired. A note in the code might be a better idea? > seems like a good thing. I'd say go ahead and commit it. OK, done with the change in the copyright/help but I have a problem here. I could svn add the source but svn refuses to commit (see message which I don't understand). right access problem? am I missing something? octave-forge/main/signal/inst$ svn status A fracshift.m octave-forge/main/signal/inst$ svn ci fracshift.m -m"first import" svn: Commit failed (details follow): svn: Server sent unexpected return value (403 Forbidden) in response to MKACTIVITY request for '/svnroot/octave/!svn/act/d893d539-3913-4ddc-ada4-448b62242a57' eric -- View this message in context: http://www.nabble.com/shift-of-a-fractional-number-of-samples-tp18490379p18493527.html Sent from the octave-dev mailing list archive at Nabble.com. ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ Octave-dev mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/octave-dev
