Matlab is a program for numeric computation and visualization. The basic data element for Matlab is a matrix. Matlab is used for general-purpose numeric computation, algorithm prototyping, and special-purpose problem solving with matrix formulations that arise in various disciplines such as automatic control theory, statistics, and digital signal processing (time-series analysis).
Matlab also has a group of application-specific solutions called "toolboxes." Toolboxes available for University of Delaware use include the following. All are available on Strauss except as noted:
Matlab is available on Strauss. You can get it by typing the matlab command. The matlab ver, from a matlab sessoin, will give you a list of all available add-on packages and their version numbers

To use all the features of Matlab on Strauss you must logon in an X-windows environment.
At the UNIX prompt, type
matlab
The Matlab Desktop will startup in a separate window. The desktop is in a
large window with pull down menus on the top, and several sub-windows including
"Current Directory", "Command History" and "Command Window". If you
are new the matlab desktop you should take some time looking at
the help system starting with Help -> Using Desktop.
The default way to run Matlab is called desktop mode, and is useful for beginners since it manages all the important tasks in one window - browsing for files, editing files, running programs, debugging etc. Matlab commands are entered in the command sub-window of the desktop window.
Advanced users can enter all matlab commands in the terminal window using command line mode. You have access to all of Matlab's commands and can program in matlab. This is a faster way to use Matlab on a slow connection, but features such as interactive graphics, demos, and some documentation are not available in command line mode.
At the Strauss UNIX prompt, type
matlab -nodesktop
The Matlab startup screen, similar to the following will appear:
< M A T L A B (R) >

To get started, type one of these: helpwin, helpdesk, or demo.

To terminate the Matlab session, at the Matlab prompt
>>, type
quit
Hints when using Matlab command line mode:
edit command you must first set
your EDITOR environment variable to your preferred
visual editor - typically vi or emacs. To run Matlab from the SunRay terminals just use the launch menu.
Launch -> UD Applications -> Matlab
This is launches Matlab on Strauss using the Sun Ray as a local X-windows environment. You can do this from your own local X-windows system by using the commnand.
ssh -Y -f username@strauss.udel.edu matlab -desktop
If you have configured ssh to connect to strauss with no password,
or you have ssh-askpass installed in your environment than
this command can be used outside of xterm. The
X11 server still needs to be running on your PC or Mac.
The details of how to use this command depends on your local environment.
If you need help quickly, you may call the IT Help Center at 831-6000 between 8 a.m. and 5 p.m., Monday through Friday. Or, you can submit a question through e-mail.
