以前在 MATLAB 中打开的 m 文件的历史记录

History of previously opened m-files in MATLAB

是否可以找到 2 或 3 个月前在 MATLAB R2014b 中打开的 m 文件的历史记录? (文件名和路径的列表)

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,因此很容易用 xmlread 加载和解析。我不是很熟悉 xml 解析语法,但这里是如何获取文件信息的方法(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

这个returns一个像这样的结构:

recentFiles = 

1x43 struct array with fields:

    AbsPath
    LastWrittenTime
    Name

注意:我尝试输入 matlab 命令 window matlab.desktop.editor.*,但似乎没有关于最近文件的任何内容 (无论如何有很多有趣的东西可以操作命令行编辑器)

最后的回答真的很有帮助。我刚刚修改它以读取和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

在 R2018b 中,您可以在 Preferences > Editor/Debugger 中增加 Most recently used file list。我喜欢上面的方法,但如果你跨机器工作(例如,使用 Github),它们就不起作用了。 I coded a solution 使用来自机器的修改文件日期,而不是依赖 MATLAB 本身。

基于 CitizenInsane 的回答,但适用于任何 Matlab 版本。

要在任何 Matlab 版本中查找 .xml 文件,请使用 prefdir:

>> prefdir

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

MATLAB_Editor_State.xml 将存储在那里。因此函数将是:

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
