+## @deftypefn {Function File} {@var{h} =} allchild (@var{handles})
+## Find all children, including hidden children, of a graphics object.
+##
+## This function is similar to @code{get (h, "children")}, but also
+## returns hidden objects.  If @var{handles} is a scalar,
+## @var{h} will be a vector.  Otherwise, @var{h} will be a cell matrix
+## of the same size as @var{handles} and each cell will contain a
+## vector of handles.
