As part of my startup.m file, I start by calling the userpath function, then genpath and lastly, addpath. I’m not certain this is the most efficient method, since my startup.m file has evolved over the 15 or so years since MATLAB added the MATLAB directory to Documents, but it works.
Specifically:
MyPath = userpath;
MyDir = MyPath(1:strfind(MyPath,';')-1);
MyWorkDir = genpath(MyDir);
addpath(MyWorkDir, '-end');
EDIT — This works for Windows. No promises for Mac or Linux systems.
