% Return the datenum of the next or previous business day from

% and the previous day if -1. @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{direction}, @var{holiday},
% @var{weekend}) are empty, then the default is used.
