MATLAB startup M-file for single-user systems or system administrators

**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 the MATLAB search path.

As an individual user, you can create a startup file in your own MATLAB directory. Use the startup file to define physical constants, engineering conversion factors, graphics defaults, or anything else you want predefined in your workspace.

**Algorithm**

Only `matlabrc`

is actually invoked by MATLAB at startup. However, `matlabrc.m`

contains the statements

that invoke `startup.m`

. Extend this process to create additional startup M-files, if required.

**Remarks**

You can also start MATLAB using options you define at the Command Window prompt or in your Windows shortcut for MATLAB.

**Turning Off the Figure Window Toolbar**

If you do not want the toolbar to appear in the figure window, remove the comment marks from the following line in the `matlabrc.m`

file, or create a similar line in your own `startup.m`

file.
