Description

Matlab integrates mathematical computing, visualization, and a powerful language to provide a flexible environment for technical computing. The open architecture makes it easy to use MATLAB and its companion products to explore data, create algorithms, and create custom tools that provide early insights and competitive advantages.

Version

After starting matlab (either commandline or X-Windows GUI), type the command ver.

Run the Matlab GUI Interactively

To run the MATLAB graphics interface, an X Windows connection is required. Open an X-Windows connection to helix.nih.gov, and check that it is working by typing 'xclock' at the prompt.

[user@helix ~]$ matlab &

You should see the Matlab windows as below:

MATLAB flash image

MATLAB desktop image

HINT: If you receive an error message that contains "Failure to Launch Desktop Class", cd to $HOME/.matlab and remove the directory R2007a and try again.

You must use X software to connect, otherwise you will not be able to run the Matlab GUI.

Run Matlab interactively without the GUI

It is also possible to run Matlab interactively on the command-line, without the GUI. This would be useful if you do not wish to use X-Windows.
