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

On Mac OS X, you may put your startup.m file in /matlabrootfolder/toolbox/local/. For example, this path might look like the following for Matlab 2012: /Applications/MATLAB_R2012a.app/toolbox/local/.

To prevent the file from being removed after upgrading Matlab, you may use a symlink to the file. If your startup file is stored at $HOME/myDir/startup.m, for example (in Bash):

cd /Applications/MATLAB_R2012a.app/toolbox/local/
ln -s ~/myDir/startup.m .
