MATLAB Function rmpath — Remove folders from search path

When I was writing blog¹, I used a simple example to show how to add all functions (or classes) within a folder, including all subfolders, into the search path. After that, however, when I wanted to delete this folder, I found I couldn’t — I didn’t have permission.

There are two methods to solve this problem:

1. Restart MATLAB and then delete, since MATLAB will automatically delete those temporary search paths after closing.
2. Use rmpath function² to remove the newly added search path, rmpath(genpath('folders')), and then I could delete it successfully.
