    20## @deftypefn {Function File} {@var{h} =} allchild (@var{handles})

    21## Find all children, including hidden children, of a graphics object.

    22##

    23## This function is similar to @code{get (h, "children")}, but also

    24## returns includes hidden objects.  If @var{handles} is a scalar,

    25## @var{h} will be a vector.  Otherwise, @var{h} will be a cell matrix

    26## of the same size as @var{handles} and each cell will contain a

    27## vector of handles.

    28## @seealso{get, set, findall, findobj}
