Question

无论如何，从2个月或3个月前在MATLAB R2014b中找到以前打开的m文件的历史记录？（文件和路径名称列表）

Answer 1

Matlab R2014b将其最近的文件存储在：

%APPDATA%\MathWorks\MATLAB\R2014b\MATLAB_Editor_State.xml

这是一个.xml文件，因此可以使用xmlread轻松加载和解析。我不是很熟悉xml解析语法，但是这里是如何获取有关文件的信息（当然要适应你的需要）：

function [recentFiles] = GetRecentFiles()
%[
    % Opens editor's state file
    filepart = sprintf('MathWorks\\MATLAB\\R%s\\%s', version('-release'), 'MATLAB_Editor_State.xml');
    filename = fullfile(getenv('APPDATA'), filepart);
    document = xmlread(filename);

    % Get information about 'File' nodes
    recentFiles = struct([]);
    fileNodes = document.getElementsByTagName('File');
    for fni = 1:(fileNodes.getLength())

       attributes = fileNodes.item(fni-1).getAttributes(); % Careful, zero based indexing !

       for ai = 1:(attributes.getLength())

           % Get node attribute
           name = char(attributes.item(ai-1).getName()); % Zero based + need marshaling COM 'string' type
           value = char(attributes.item(ai-1).getValue()); % Zero based + need marshaling COM 'string' type

           % Save in structure
           name(1) = upper(name(1)); % Just because I prefer capital letter for field names ...
           recentFiles(fni).(name) = value;

       end

    end    
%]
end

这将返回如下结构：

recentFiles = 

1x43 struct array with fields:

    AbsPath
    LastWrittenTime
    Name

注意：我尝试输入matlab命令窗口matlab.desktop.editor.*，但似乎没有关于最近的文件（无论如何，从命令行操作编辑器有很多有趣的事情）< / em>的

最后回答waIs真有帮助。我刚修改它以阅读并打开最近的标签文件。这适用于Matlab R2013a：

function [recentFiles] = recover_tabs()
%[
% Opens editor's state file
filepart = sprintf('MathWorks\\MATLAB\\R%s\\%s', version('-release'), 'MATLAB_Editor_State.xml');
filename = fullfile(getenv('APPDATA'), filepart);
document = xmlread(filename);

% Get information about 'File' nodes
recentFiles = struct([]);
fileNodes = document.getElementsByTagName('File');
for fni = 1:(fileNodes.getLength())

   attributes = fileNodes.item(fni-1).getAttributes(); % Careful, zero based indexing !

   for ai = 1:(attributes.getLength())

       % Get node attribute
       name = char(attributes.item(ai-1).getName()); % Zero based + need marshaling COM 'string' type
       value = char(attributes.item(ai-1).getValue()); % Zero based + need marshaling COM 'string' type

       % Save in structure
       name(1) = upper(name(1)); % Just because I prefer capital letter for field names ...
       recentFiles(fni).(name) = value;

   end

end    

%     loop to access files in the tab history
for j=1:length(recentFiles)
    arquivo = [recentFiles(j).AbsPath '\' recentFiles(j).Name];
%         if exists, then open
    if exist(arquivo, 'file') == 2
        open(arquivo);
    end
end

%]
end

Answer 3

基于CitizenInsane的答案，但适用于任何Matlab版本。

要找到任何Matlab版本的.xml文件，请使用prefdir：

>> prefdir

ans =  '/Users/user/Library/Application Support/MathWorks/MATLAB/R2018a'

MATLAB_Editor_State.xml将存储在此处。因此功能将是：

function [recentFiles] = GetRecentFiles()

% Opens editor's state file
filepart = sprintf([ prefdir '/MATLAB_Editor_State.xml']);
filename = fullfile(getenv('APPDATA'), filepart);
document = xmlread(filename);

% Get information about 'File' nodes
recentFiles = struct([]);
fileNodes = document.getElementsByTagName('File');
for fni = 1:(fileNodes.getLength())

   attributes = fileNodes.item(fni-1).getAttributes(); % Careful, zero based indexing !

   for ai = 1:(attributes.getLength())

       % Get node attribute
       name = char(attributes.item(ai-1).getName()); % Zero based + need marshaling COM 'string' type
       value = char(attributes.item(ai-1).getValue()); % Zero based + need marshaling COM 'string' type

       % Save in structure
       name(1) = upper(name(1)); % Just because I prefer capital letter for field names ...
       recentFiles(fni).(name) = value;

   end

end

Answer 4

在R2018b中，您可以在Most recently used file list中增加Preferences > Editor/Debugger。我喜欢上面的方法，但是如果您跨机器工作（例如，使用Github），则它们将不起作用。 I coded a solution使用来自计算机的修改文件日期，而不是依赖MATLAB本身。

先前在MATLAB中打开的m文件的历史
