For me the generatemsgid function is in toolbox\shared\spcuilib\. Maybe that folder got removed from your search path somehow, or it just does not exist. In any case, the generatemsgid function is used to display errors, so if you can figure out how to call buttord without otherwise producing an error, the fact that you are missing that file won't matter. You could just edit that line of buttord to throw the error without calling generatemsgid (just error(msg))
(Incidentally, running the line you show gives the error message is "The cutoff frequencies must be within the interval of (0,1)")![]()
