Starting and Quitting MATLAB (Development Environment)

Development Environment

Adding Startup Options for UNIX Platforms

Include startup options (also called command flags) after the matlab startup command.

For example, to start MATLAB without the splash screen, type

```
matlab -nosplash
```

For more details, see the matlab reference page.

Option
Description

-arch
Run MATLAB assuming architecture arch.

-arch/ext
Run the version of MATLAB with the extension ext, if it exists, assuming architecture arch.

-c licensefile
Set LM_LICENSE_FILE to licensefile. It can have the form port@host.

-check_malloc
Set the MATLAB_MEM_MGR environment variable to 'debug'. This starts MATLAB memory integrity checking.

-Ddebugger [options]
Start MATLAB with the specified debugger.

-debug
Turn on MATLAB internal debugging.

-display Xserver
Send X commands to Xserver.

-ext
Run the version of MATLAB with the extension ext, if it exists.

-h or -help
Display startup options (without starting MATLAB).

-logfile log
Make a copy of any output to the Command Window in the file log. This includes all crash reports.

-mwvisual visualid
Specify the default X visual to use for figure windows.

-n
Display final values of environment variables and arguments passed to MATLAB (without starting MATLAB).

-nodesktop
Start MATLAB without bringing up the MATLAB desktop. Use this option to run without an X-window, for example, in VT100 mode, or in batch processing mode. Note that if you pipe to MATLAB using the > constructor, the nodesktop option is used automatically.
With nodesktop, you can still use most development environment tools by starting them via a function. Specifically use
edit to open the Editor/Debugger

helpbrowser to open the Help browser

filebrowser to open the Current Directory browser

workspace to open the Workspace browser

openvar to open the Array Editor

profile viewer to open the Profiler

You cannot use the LaunchPad and the Command History window in -nodesktop mode.
Don't use nodesktop to provide a command line interface. If you prefer a command line interface, select View -> Desktop Layout -> Command Window Only.

-nojvm
Start MATLAB without loading the Java VM. This minimizes memory usage and improves initial startup speed. With nojvm, you cannot use the desktop, or any of the tools that require Java. The restrictions are the same as those described under Platform Limitations in the Release Notes.

-nosplash
Start MATLAB without displaying the splash screen during startup.

Option	Description
`-arch`	Run MATLAB assuming architecture `arch`.
`-arch/ext`	Run the version of MATLAB with the extension `ext`, if it exists, assuming architecture `arch`.
`-c licensefile`	Set `LM_LICENSE_FILE` to `licensefile`. It can have the form `port@host`.
`-check_malloc`	Set the `MATLAB_MEM_MGR` environment variable to '`debug`'. This starts MATLAB memory integrity checking.
`-Ddebugger [options]`	Start MATLAB with the specified debugger.
`-debug`	Turn on MATLAB internal debugging.
`-display Xserver`	Send X commands to `Xserver`.
`-ext`	Run the version of MATLAB with the extension `ext`, if it exists.
`-h or -help`	Display startup options (without starting MATLAB).
`-logfile log`	Make a copy of any output to the Command Window in the file `log`. This includes all crash reports.
`-mwvisual visualid`	Specify the default X visual to use for figure windows.
`-n`	Display final values of environment variables and arguments passed to MATLAB (without starting MATLAB).
`-nodesktop`	Start MATLAB without bringing up the MATLAB desktop. Use this option to run without an X-window, for example, in VT100 mode, or in batch processing mode.
