matlab如何遍历所有子文件里面

在MATLAB中，遍历文件夹以及其所有子文件夹通常使用`cd`和`dir`函数结合递归搜索。以下是一个基本的示例，展示如何遍历整个目录树，并打印出所有的文件和子目录名：

function traverseDirectory(path)
% Set the starting directory
currentDir = path;

% Use a while loop to continue until there are no more subdirectories
while ~isempty(currentDir)
    % Get the list of all files and directories in this level
    contents = dir(fullfile(currentDir, '*'));

    for i = 1:length(contents)
        % Check if it's a directory or a file
        if isdir(fullfile(currentDir, contents(i).name))
            fprintf('Found subdirectory: %s\n', fullfile(currentDir, contents(i).name));
            % Recursively call the function on the subdirectory
            traverseDirectory(fullfile(currentDir, contents(i).name));
        else
            fprintf('Found file: %s\n', fullfile(currentDir, contents(i).name));
        end
    end
    
    % Move up one level (back to parent directory) before exploring next level
    currentDir = cd ..
end
end

% Call the function with your root directory path
traverseDirectory('your_directory_path');

这段代码会进入指定的文件夹，然后逐层递归地检查每个子目录内的文件和子目录，直到所有层次都被访问过。
