3. AI – CS289 Fuzzy Logic - Labs 05 th October 2006Bogdan L. Vrusias © 20063 Working Environment Three ways to run Matlab: –On a Windows environment (using a terminal emulation software like Exceed) –On the BB Linux labs –A third way would be to download a 30 day trial version of Matlab on your own PC.

4. AI – CS289 Fuzzy Logic - Labs 05 th October 2006Bogdan L. Vrusias © 20064 Windows Environment (AP labs) i.e. AP2 labs Go to: –Start>All Programs>Unix Login, FTP & Client>EE Tweek You should see a window like: Type in your username and password and you should then get a terminal window. On the terminal window type: matlab &

5. AI – CS289 Fuzzy Logic - Labs 05 th October 2006Bogdan L. Vrusias © 20065 Windows Environment 2 i.e. Your own computer (from within the campus) Skip this if you are in the AP labs!!! Run a telnet window: –E.g. Start>Run and then type: telnet tweek.ee.surrey.ac.uk Login, and then, on the telnet window type: setenv DISPLAY 131.227.68.123:0.0 Where 131.227.68.123 is your computer’s IP address, or alternately you may enter the computer’s network name. then type: matlab &

9. AI – CS289 Fuzzy Logic - Labs 05 th October 2006Bogdan L. Vrusias © 20069 Exploring the Fuzzy Logic Toolbox OPTIONAL Download and unzip the following file, that contains lots of fuzzy examples in Matlab: http://www.booksites.net/download/negnevitsky2/student_files/matlab/0321204662_matlab.zip or alternately: http://www.cs.surrey.ac.uk/teaching/cs289/lecturenotes/0321204662_matlab.zip Using the Fuzzy Logic Toolbox GUI, open a file from the ones you just downloaded (and unzipped): –File>Import>From Disk Use the menu options to see the rules, fuzzy graphs, etc. NOTE: You are not yet expected to understand the given Matlab examples. The purpose of today’s exercise is to make sure you can all login and load Matlab.

10. AI – CS289 Fuzzy Logic - Labs 05 th October 2006Bogdan L. Vrusias © 200610 Problems? If you get into any technical problems: –Try to see the AP student support representative –If the problem persists, email me. It is important that we sort out all problems loading and using Matlab before the next lab.
