matlabrc initializes the MATLAB^® program. At startup, MATLAB automatically executes matlabrc and then the startup script, if it exists.

For system administrators managing multi-user or networked systems, modify matlabrc to add messages, definitions, or other code that applies to all users. The matlabrc script is in the matlabroot/toolbox/local folder.

For individual systems, use the startup script to customize MATLAB startup. Put this script in the userpath folder.
