allchild.m

这是MATLAB小型的。下下去看看嘛

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.
%
%   For example, try get(gca,'children') and allchild(gca).
%
%   See also GET, FINDALL.
