MATLAB Function Reference

startup - Startup M-file for user-defined options

Syntax

startup

Description

startup automatically executes the master M-file matlabrc.m and, if it exists, startup.m, when the MATLAB^® program starts. 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 the search path MATLAB uses.

You can create a startup.m file in your own startup directory for MATLAB. The file can include physical constants, defaults for Handle Graphics^® properties, engineering conversion factors, or anything else you want predefined in your workspace.

There are other ways to predefine aspects of MATLAB. See Startup Options and About Preferences in the MATLAB Desktop Tools and Development Environment documentation.

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.
