本文介绍了一个用于Matlab的自定义函数getFiles，该函数能够递归地获取指定目录及其子目录下的所有文件路径，并将这些路径保存在一个单元数组中返回。通过对当前文件和子目录的判断及处理，确保了所有文件都能被正确地记录。

function returnFiles=getFiles(baseDir)
% get files in a directory
%input baseDir: is the directory for get Files,it must be a string end with
%'/'
%output returnFiles:is a cell of file paths in the directory
files=dir(baseDir);
%m is the numbers of the files contained in the directory
[m,tmp]=size(files);
%returnFiles is a cell for storing the file paths
%it is set to size of 1 and storing 'Files are:' for the state that there is no files
%in the directory
returnFiles=cell(1);
returnFiles{1}='Files are:';
for i=1:m
    %processing erery file
    current=files(i);
    %get the file name
    file_name=current.name;
    %processing with the state of '.' and '..'
    if strcmp(file_name,'.')==1 || strcmp(file_name,'..')==1
        continue;
    end
    if current.isdir==1
        % if it is a directory
        % get the diretory path
        currentDir=strcat(baseDir,strcat(file_name,'/'));
        %processing the sub direcotry
        tmpReturnFiles=getFiles(currentDir);
        %save the files contained in the subdir to the cell of returnFiles
        %processing with the state that there is no file in the subdir
        if strcmp(tmpReturnFiles{1},'Files are:')==0
            %processing with the state that there is no file stored in the
            %cell of returnFiles
            if strcmp(returnFiles{1},'Files are:')==1
                returnFiles=tmpReturnFiles;
            else
                %merge the files in current dir and the files in the subdir
                returnFiles=[returnFiles,tmpReturnFiles];
            end
        end
    else
        % get the file path of the file
        filePath=strcat(baseDir,file_name);
        %to find that if there is any file stored in the cell
        if strcmp(returnFiles{1},'Files are:')==1
            % if there is no file stored in the cell,than save current file
            % to the first cell
            returnFiles{1}=filePath;
        else
            % if there is any file stored in the cell,than merge
            returnFiles=[returnFiles,{filePath}];
        end
    end
end
