User-defined startup script for MATLAB



startup executes user-specified commands when starting.

Create a startup.m file in the userpath folder, which is on the MATLAB® search path. Add commands you want executed at startup. For example, your startup function might include physical constants, defaults for graphics properties, engineering conversion factors, or anything else you want predefined in your workspace.


  • To specify the current folder in MATLAB when it starts, set the Initial working folder preference, described in General Preferences.


At startup, MATLAB automatically executes the matlabrc function and, if it exists on the MATLAB search path, startup. The matlabrc file, which is in the matlabroot/toolbox/local folder, is reserved for use by MathWorks® and by system administrators on multiuser systems.
