## @defmethod {@@infsupdec} linspace (@var{BASE}, @var{LIMIT})
## @defmethodx {@@infsupdec} linspace (@var{BASE}, @var{LIMIT}, @var{N})
##
## Return a row vector of @var{N} linearly spaced members between @var{BASE}
## and @var{LIMIT}.
##
## If @var{BASE} is greater than @var{LIMIT}, members are returned in
## decreasing order. The default value for @var{N} is 100.
##
## If either @var{BASE} or @var{LIMIT} is not a scalar, the result is a matrix.
##
## Accuracy: The result is an accurate enclosure.
##
## @example
## @group
## transpose (linspace (infsupdec (0), infsupdec (10), 4))
