function ChildList=allchild(HandleList)

%ALLCHILD Get all object children

%   ChildList=ALLCHILD(HandleList) returns the list of all children 

%   (including ones with hidden handles) for each handle.  If 

%   HandleList is a single element, the output is returned in a 

%   vector.  Otherwise, the output is a cell array.

%

%   Example:

%       h_gca = gca;

%       h_gca.Children

%           %or

%       allchild(gca)
