MATLAB与 *.m 文件关联

Matlab关联m文件

首先将以下代码复制到matlab中，然后保存到桌面上为associateFiles.m文件。

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.

然后点击运行，会出现【MATLAB 编辑器】对话框，点击【更改文件夹】选项，运行即可。

这时会在自己桌面上出现【MatlabFileAssocFix.reg】文件，双击打开运行即可。
