MATLAB

MATLAB is an integrated technical computing environment that combines numeric computation, advanced graphics and visualisation, and a high-level programming language.

Whatever the objective - an algorithm, analysis, graph, report, or simulation - MATLAB gets you there. The flexible, interactive MATLAB language lets engineers and scientists express their technical ideas simply. The extensive and powerful numeric computing methods and graphics allow testing and exploring alternative ideas easily, while the integrated development environment makes it easy to produce fast, practical results.

The latest version licensed by METU is available at ftp://ftp.cc.metu.edu.tr/PackagePrograms/Matlab/ and runs on these platforms: MS Windows NT/2000/XP/2003,/Vista, HP-UX, Linux, MacOS. 

Toolboxes of Matlab Software are as follows:

Simulink
Control System Toolbox
System Identification Toolbox
Image Processing Toolbox
Mapping Toolbox
Neural Network Toolbox
Optimization Toolbox
Signal Processing Toolbox

Statistics Toolbox
Financial Toolbox
Financial Derivatives Toolbox
GARCH Toolbox
Wavelet Toolbox
Simulink Control Design
Fixed-Point Toolbox
Stateflow, Bioinformatics and Simbiology.

You can start a Matlab session on orca and beluga servers by entering "matlab" on the command line. To run matlab on servers and to use X-Windows environment please read  Information about XWINPRO and Cygwin/XFree86.

You can get the PC program source from licensed software ftp site:

 ftp://ftp.cc.metu.edu.tr/PackagePrograms/Matlab/, 

Notice: Users, who would connect to the FTP licensed software site with a browser other than Internet Explorer, shall write ftp://user_name@ftp.cc.metu.edu.tr to the address line. Due to the license agreements that are made, this site is accessible to METU personnel only.

Installation of Matlab for Windows:

For the installation of Matlab you need for a file named "license.dat". This file can be created by "notepad"or a similar text editor. There should be lines below, in the file content:

SERVER beluga.cc.metu.edu.tr INTERNET=144.122.144.11 27005
USE_SERVER

During installation, depending on the version of Matlab, a "PLP password" or "File Installation Key" is required. You can find this PLP password and "File Installation Key" in Matlab directory at ftp.cc address given above or get it by sending an e-mail to swadminmetu.edu.tr.

Installation of Matlab for Linux:

For the installation of Matlab, a file named "license.dat" is needed. This file can be created by any text editor. Following line should be in the content of file:

SERVER beluga.cc.metu.edu.tr INTERNET=144.122.144.11 27005
USE_SERVER

Also it is necessary to write the following information

144.122.144.11          beluga.cc.metu.edu.tr

to /etc/hosts file in system. Please DO NOT COPY the line above directly from the text, but write again (Before writing #PRE, please remember to leave a blank space with "tab" key, not with "space" key.)

Important Note:

1) The older versions of Matlab Software, before 6.5 (R13), has only Simulink and Control System Toolboxes. Users who want to use the other toolboxes, should install Matlab 6.5 (R13)

2) Users, who installed Windows version of Matlab 6.5 (R13), before 23/06/2003, should install additional toolboxes with new PLP number, for installing toolboxes except Simulink and Control System toolboxes. There is no need to install the software completely again, an making a change in license file. Linux version users don not have to make any change on their settings. It is enough to restart the installation and to add new toolboxes.

Frequently Asked Questions About Matlab

Q: I am running out of disc space because of the files that are automatically created whenever I run the software and/or the output files that I myself have created, can you increase my quota limits?
A: We have created a directory named "/temp" on central servers systems (such as beluga, orca, narwhal, rorqual, tasman); so that our users can execute and work with oversize files without experiencing disc space problems. By creating another directory within the "/temp" folder, you can carry out tasks and perform your operations. To create another directory within "/temp" folder, use the following command: "mkdir directory_name". You should be mindful of the fact that other users may also need space within this folder; so, after you are done with your work, do not forget to delete all the files you have created in the folder.

Q: Although I specify the location of the license file as I am trying to install the software, "file not found" error message is being displayed. What should I do?
A: When the system prompts the location of the license file, you should specify only the directory of the license file; do not include the file name.
e.g.: If the license file is located in the following path C:\Program Files\Matlab\, you should specify the location as C:\Program Files\Matlab\ (If you specify the location as C:\Program Files\Matlab\license.dat, it is highly probable that you will receive an error message).

Q: I want to use the software from outside METU. How can I do it?
A: METU is bound by the restrictions which are arranged and specified expressly in the terms of software license agreements. According to these agreements, the licensed software can only be used solely for academic purposes and strictly within the boundaries of METU. It is expressly forbidden to use the software from outside METU.
