How to find all specified files in a specified path in Matlab？matlab 如何查找指定路径下的所有指定文件

Matlab 如何遍历所有文件下以及子文件中的模型文件（.mdl ,.slx）

How Matlab Traverses Model Files in All Files and Subfiles

Answer 1

[Xiaoning.Wang]

可以查看两个help 文件

listing = dir('*.txt'); % 列出当前文件夹中所有的txt文件

listing = dir('*.txt'); % 返回当前文件夹下所有.txt文件的信息

listing = dir('**/*.txt'); % 返回当前文件夹及子文件夹中所有.txt文件的信息

映射出

listing1 = dir('Z:/model/**/*.slx');

listing2 = dir('Z:\model\**\*.slx');

如果你想查询两个不同格式文件的模型

listing = [dir('**\*.slx');dir('**\*.mdl')]

Hi, @Xiaoning.Wang

你可以使用 dir 函数结合递归来遍历文件夹及其子文件夹中的所有 .mdl 和 .slx 文件。以下是一个示例代码：

function files = findModels(directory)
    % Initialize an empty cell array to store model file paths
    files = {};
    % Get a list of all files and folders in the specified directory
    fileList = dir(directory);
    
    % Loop through the files/folders
    for i = 1:length(fileList)
        % Skip the '.' and '..' entries
        if strcmp(fileList(i).name, '.') || strcmp(fileList(i).name, '..')
            continue;
        end
        
        % Get the full path of the current file/folder
        fullPath = fullfile(directory, fileList(i).name);
        
        % If it's a folder, recurse into it
        if fileList(i).isdir
            files = [files, findModels(fullPath)];  % Recursion
        else
            % If it's a model file, add it to the list
            if endsWith(fileList(i).name, {'.mdl', '.slx'})
                files = [files, fullPath];
            end
        end
    end
end

调用 findModels 函数并传入目录路径，函数将返回该目录及所有子目录中 .mdl 和 .slx 文件的路径。

挺好的，如果这个function这么写，就具有很好的普适性了，很多类型的文件都能用了。

function files = findModels(directory,FileType)

% Initialize an empty cell array to store model file paths

files = {};

% Get a list of all files and folders in the specified directory

fileList = dir(directory);

% Loop through the files/folders

for i = 1:length(fileList)

% Skip the '.' and '..' entries

if strcmp(fileList(i).name, '.') || strcmp(fileList(i).name, '..')

continue;

end

% Get the full path of the current file/folder

fullPath = fullfile(directory, fileList(i).name);

% If it's a folder, recurse into it

if fileList(i).isdir

files = [files, findModels(fullPath,FileType)]; % Recursion

else

% If it's a model file, add it to the list

if endsWith(fileList(i).name, FileType)

files = [files, fullPath];

end

end

end

end

如果你只需要文件名，可以用ls

ls *.mdl
ls *.slx
