startup (MATLAB Functions)

MATLAB startup M-file for user-defined options

Description

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

You can create a startup.m 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.

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.
