如何将@class文件夹重置为原始状态 [英] How to reset @class folder to native state

问题描述

我无意中弄乱了我的matlabroot文件夹，现在某些功能坏了.如何重置文件夹的状态，以便一切都能正常工作?

I have inadvertently messed around with my matlabroot folder and now some functionality is broken. How do I reset the state of the folder so that everything works again?

在尝试解决此问题，我向@table文件夹([matlabroot,'\toolbox\matlab\datatypes\@table\*'])添加了一个新方法(nansubset.m).那没有用，所以我按照@TroyHaskin的回答建议将其删除，然后将其移至我的Matlab路径.一切正常，直到我重新启动Matlab.现在，我收到错误消息:

While trying to solve this question, I added a new method (nansubset.m) to the @table folder ([matlabroot,'\toolbox\matlab\datatypes\@table\*']). That did not work so I deleted it and moved it to my Matlab path as suggested by @TroyHaskin's answer. Everything worked fine until I restarted Matlab. Now I am getting the error message:

Error using table/nansubset
Previously accessible file "C:\Program
Files\MATLAB\R2015b\toolbox\matlab\datatypes\@table\nansubset.m" is now inaccessible.

我尝试了clear classes和clear java并重新启动Matlab，但无济于事.

I have tried clear classes and clear java and restarting Matlab, to no avail.

我还在Mathworks网站上找到了此链接，将我带到了则建议使用rehash toolboxcache.我这样做了，现在有一个新的错误消息:

I also found this link on the Mathworks site, which led me to doc toolbox_path_cache that in turn suggests using rehash toolboxcache. I did this and now there is a new error message:

Error using table/nansubset
Method 'nansubset' is not defined for class 'table' or is removed from MATLAB's search path.

但是，which nansubset从Matlab路径上的目录返回正确的文件.

However, which nansubset returns the right file from a directory on my Matlab path.

推荐答案

我已经解决了我的问题.本质上，按照此处的说明，我们将转到toolbox_path_cache的"http://au.mathworks.com/help/matlab/matlab_env/toolbox-path-caching-in-the-matlab-program.html" rel ="nofollow">帮助文件，其中状态:

I have fixed my problem. Essentially, following the instructions from here, we are led to the helpfile for toolbox_path_cache, which states:

某些人在matlabroot/toolbox文件夹中添加或删除文件时 其他方式，MATLAB可能无法识别这些更改.

When you add or remove files in matlabroot/toolbox folders by some other means, MATLAB might not recognize those changes.

...

更新缓存，以便MATLAB识别 您在matlabroot/toolbox文件夹中所做的更改.

Update the cache so MATLAB recognizes the changes you made in matlabroot/toolbox folders.

要更新缓存，请键入rehash toolbox和rehash toolboxcache.之后，有必要重新启动Matlab来解决问题

To update the cache, type rehash toolbox and rehash toolboxcache. After this, it was necessary to restart Matlab to fix the problem
