Matlab 如何将结果存储在递归函数中

我有一个matlab函数，用于列出文件夹中的所有文件，包括其子文件夹。我可以全部显示它们，但我不知道如何将它们存储在我的输出变量中

function out = searchfolder(varargin)
if nargin<1
    helpdlg('no input floder');
    return;
else
curfolder=varargin{1};
end
if ~isdir(curfolder) || length(dir(curfolder)) < 3
return;
end

children = dir(curfolder);
%eliminate '.' and '..' 
children = children(3:end);
allfiles = {};
for i=1:length(children)
   child = children(i);
   thisone = fullfile(curfolder,child.name);
    if child.isdir
       searchfolder(thisone);
    else
       disp(thisone);

    end
end

function out=searchfolder（varargin）
如果nargin在excaza的帮助下，我有代码：

function out = searchfolder(varargin)
out = {};
if nargin<1
%        helpdlg('no input floder');
    return;
else
curfolder=varargin{1};
end
if ~isdir(curfolder) || length(dir(curfolder)) < 3
return;
end 
children = dir(curfolder);
%eliminate '.' and '..' 
children = children(3:end);
allfiles = {};
for i=1:length(children)
   child = children(i);
   thisone = fullfile(curfolder,child.name);
    if child.isdir
       out = [ out ;searchfolder(thisone)];
    else
       disp(thisone);
    out = [out;{thisone}];
    end
end

function out=searchfolder（varargin）
out={}；
如果需要连接递归
searchfolder
调用的输出。e、 g.
out=[out searchfolder（thisone）]
（初始化输出后）好的，谢谢@excaza，我会试试
