Matlab functions
Add library on search path with
addpath(genpath(fullfile(getenv('HOME'),'lib/matlab')))
Alternatively, if lib is linked to say, lib in the userpath (which is ~/Documents/MATLAB) on OSX, one of two methods can be used:
addpath(fullfile(strrep(userpath,':',''),'lib'))
addpath(fullfile(fileparts(userpath),'MATLAB/lib'))
