I'm currently creating a series of matlab m-files which are monitored by SVN. The m-files are located in different sub-directories. Some of them are sub-functions and are called by a lot of different m-files. This sub-functions need some other sub-(sub-)functions and would need a use of addpath to reach them. But due to the fact that other people will retrieve my m-files in their home space, I cannot use absolute paths... And the use of relative paths with addpath for sub-functions is not possible because addpath works inside the working path, not from the place where the m-file which call it is located.
I know that SVN is used for matlab code, so I would like to know how these links are managed without using this kind of code at the begining of each function:
