startup (MATLAB Function Reference)

Run MATLAB startup M-file

Syntax

startup

Description

At startup time, MATLAB automatically executes the master M-file matlabrc.m and, if it exists, startup.m. On multiuser or networked systems, matlabrc.m is reserved for use by the system manager. The file matlabrc.m invokes the file startup.m if it exists on MATLAB's search path. You can create a startup file in your own MATLAB directory. The file can include physical constants, handle graphics defaults, engineering conversion factors, or anything else you want predefined in your workspace.

Algorithm

Only matlabrc.m is actually invoked by MATLAB at startup. However, matlabrc.m contains the statements

if exist('startup')==2
    startup
end

that invoke startup.m. You can extend this process to create additional startup M-files, if required.

Remarks

You can also start MATLAB using options you define at the command line or in your Windows shortcut for MATLAB. See Chapter 2 of Using MATLAB for details.
