.m文件与matlab的关联

Myth丶恋晨 2021-11-22 23:12 405阅读 0赞

## .m文件不显示默认图标，变为文本文件图标怎么办？ ##

遇到这种问题网上常见的两种解决方式就是：

1.  删注册表，然后重新关联matlab starter，但是你会发现这样关联之后，并不是你想要的图标，而是和matlab.exe一模一样的图标。
2.  帮助文档。
    
     *  打开matlab的帮助文档，输入Windows File Associations，回车，找到名为Starting the MATLAB Program on Windows Platforms标题的帮助文档
     *  在这个帮助文档的最后一个小节，其小标题名为：Utilities to Set Up File Associations on Windows Platforms。找到该小节最后一行，点击（ utility to associate MATLAB with all of these file types: FIG, M, MAT, MDL, MEX, and P）即可自动恢复。  
        然而我并没有找到名为Starting the MATLAB Program on Windows Platforms的帮助文档。
3.  重装matlab。然而并不能解决问题。

几经周折，终于找到了[这篇博客][Link 1]。  
[下载链接][Link 2]。

使用方法：

*  将associateFiles.m添加到当前工作路径
 *  命令行中输入associateFiles
 *  回车，生成MatlabFileAssocFix.reg文件
 *  运行这个reg文件
 *  重启MATLAB

如果不想下载文件，可直接复制下面的代码添加到matlab工作路径：

function associateFiles(action, userExtList, fileStr)
    
    % associateFiles(action, extList, fileStr)
    %
    % Makes a registry files that can be used to set correct file associantions on
    % a windows platform. The following MATLAB file extensions are supported:
    % .m, .mat, .fig, .mexw32, .mexw64, .p, .mdl, .mdlp, .slx, .mldatx, .req,
    % .sldd, .slddc, .slxp, .sltx, .mn, .mu, .muphlp, .xvc, .xvz, .ssc, .mlapp,
    % .mlappinstall, .mltbx, .mlpkginstall, .mlprj
    %
    % INPUT:
    % action  - optional string. 
    %           * 'add' (default) adds/rewrites the MATLAB file association registry
    %              keys for this version.
    %           * 'delete' deletes the MATLAB file association registry entries for
    %              ALL versions of MATLAB (including "old style" ones)
    %           * 'deleteadd' is the same as 'delete' followed by 'add'  
    % extList - optional string or cell array of strings containing the file
    %           extensions that should be associated with this version. Default is
    %           all MATLAB file extension (see above).
    % fileStr - optional string with the name of the registry file to be written 
    %           (possibly including path). Default is the file
    %           'MatlabFileAssocFix.reg' in the current directory.
    %
    % USAGE:
    % 1) Run with desired options (see above). A registry file should have been 
    %    created. 
    % 2) Exit all running instances of MATLAB.
    % 3) Make a backup copy of the windows registry if you need to restore the 
    %    changes, see https://support.microsoft.com/en-us/kb/322756
    % 4) Double click on the created file (possibly need to enter a password) and
    %    confirm.
    % 5) Restart Windows (or explorer.exe).
    % 6) The MATLAB files should now be associated with the MATLAB version that the
    %    registry file was created in and e.g. m-files should be opened in an
    %    already running instance of MATLAB.
    %
    % EXAMPLES:
    % * associateFiles('deleteadd') - Makes a registry files that deletes all
    %   previous MATLAB file association registry keys and write new ones that
    %   associates all MATLAB files with the MATLAB version that the registry file
    %   was created in.
    % * associateFiles('', {'.m', '.mat', '.fig'}, 'myFile') - Makes a registry file
    %   "myFile.reg" that associates m-, mat- and fig-files with the MATLAB version
    %   that the registry file was created in.
