It looks like you are mixing \ and /, which might cause issues.
In general you should use filesep or fullfile to create a path out of component folder names. Also, cd is almost never needed. Most functions can be handed a full or relative path and can read files just fine. Using cd forces Matlab to check the new folder for functions and to check if any of the previously cached functions should be reloaded because the function precedence might have changed as a result.
