## @deftypefn {Function File} {} multiplt (@var{xn}, @var{yn})
## Sets and resets multiplt mode.
##
## If the arguments are non-zero, @code{multiplt} will set up multiplt
## mode with @var{xn}, @var{yn} subplots along the @var{x} and @var{y}
## axes. If both arguments are zero, @code{multiplt} closes multiplt
## mode.
