Where is startup.m supposed to be?

Question

I\'ve been chasing the answer to this question in the MATLAB documentation for a long time...

For example, at the bottom of

This is meant as a pointer for Lx users (as confused as I was at first...). I work on Debian based boxes, but the same should apply to the CentOS system lineup, etc.

• Check that after install you do have the directory/ies: ~/.matlab/
  Note that you may have several releases there as is my case. matlab actually permits that.
• Create ~/.matlab/startup.m
  Incidentally I also created my directory Workspace there. That's completely optional
• In your Matlab window's Home tab find the menu iten/icon Set Path, click on it and add a "matlab search path" with the button Add folder top left. Add ~/.matlab as a new search path. Change should take effect immediately.
• Restart Matlab to check that the content of ~/.matlab/startup.m is correctly taken into account at launch time.

I hate GUIs... I thought you might want to know ;-) HTH.
