Linux平台
问题1 MATLAB无法保存路径更改。
解决 这是由于pathdef.m权限不足，在MATLAB安装目录下：
sudo chmod a+wr toolbox/local/pathdef.m
问题2 如何将MATLAB的快捷方式添加至Ubuntu桌面？
解决 下载matlab-support：
sudo apt-get install matlab-support
按照要求完成安装后，即可在/usr/share/applications目录下找到MATLAB的快捷方式。将其复制至桌面即可。
在任意位置输入如下指令后
sudo chmod -R a+rw ~/.matlab
可以使用matlab命令直接打开MATLAB图形界面，使用matlab -nojvm -nodisplay -nosplash指令可以以命令行的方式使用MATLAB（貌似一般用不到这个吧……）
问题3 不适应on Linux下默认的Emacs快捷键
解决 Home - Preferences - Keyboard - Shortcuts，在Active settings选项中，下拉选择Windows Default Set即可。
另，Linux对大小写有严格的要求，对一个用惯Windows版本的人来说，确实需要小小的适应一下。
Windows平台
问题1 安装完成后，未在桌面或开始菜单中生成快捷方式。
解决 重新打开安装程序，选择一个比较小的组件（比如MATLAB）重新安装，在安装过程中会提示是否在桌面或开始菜单生成快捷方式。
问题2 安装完成后，MATLAB不能自动识别相关扩展名。
解决 在MATLAB中运行该脚本，该脚本会在当前目录下生成一个.reg文件（注册表文件），双击.reg文件将配置写入注册表即可。

| % | |
| % 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. | |
