## Return the datenum of the first business day of the @var{year} and
## @var{month}. @var{holiday} is a vector of datenums that defines the
## holidays observed (the holidays function is used if not given).
## @var{weekend} defines the days of the week that should be considered
## weekends; [1 0 0 0 0 0 1] (default) indicates that Sunday and
## Saturday are holidays.
##
## If any of the optional inputs (@var{holiday}, @var{weekend}) are
## empty, then the default is used.
