在MATLAB中先前打开的m文件的历史记录 [英] History of previously opened m-files in MATLAB

问题描述

是否仍要在2个月或3个月前在MATLAB R2014b中查找以前打开的m文件的历史记录? (文件和路径的名称列表)

Is anyway to find history of previously opened m-files in MATLAB R2014b from 2 or 3 months ago? (a list of name of files and paths)

推荐答案

Matlab R2014b将其最近的文件存储在以下位置:

Matlab R2014b stores its recent files in:

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

这是一个.xml文件，因此可以很容易地使用xmlread进行加载和解析.我对xml解析语法不是很熟悉，但是这里是如何获取有关文件的信息(当然要适应您的需求):

It's a .xml file so it's easy to load and parse with xmlread. I'm not very familiar with xml parsing syntax, but here is how to get information about files (to be adapted to your needs of course):

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:我试图在matlab命令窗口matlab.desktop.editor.*中键入，但似乎与最新文件无关(无论如何，有很多有趣的事情可以从命令行操作编辑器)

NB: I've tried to type in matlab command window matlab.desktop.editor.*, but seems there's nothing regarding recent files (anyway there are a lot of interesting things to manipulate the editor from the command line)
