The leading + means, that the contents of the folder is a package and has e.g. its own name space. See http://www.mathworks.com/help/matlab/matlab_oop/scoping-classes-with-packages.html

By the way: Instead of waiting for the answer in this forum, you will get a faster solution, if you ask an internet search engine for "Matlab folder +".

[Guillaume]

Note that you must not add package folders (those that start with +) to matlab's path. If you do, it's probably going to break things. Package folders are automatically considered to be on the paht by matlab as long as their containing folder is on the path.

Same with @ folders. These are classes, and they must not be added to the path. Only their containing folder.

Funnily enough, this is the first posts I found with the Google search 'matlab "+" folders'. Also, has Matlab changed how paths work? I included the parent folder for my "+" directory and nothing seems to work.
