Unformatted text preview: 14:440:127– Introduction to Computers for Engineers Notes for Lecture 01 Rutgers University, Spring 2010 Instructor Blase E. Ur 1 What Is Matlab? Matlab (‘MATrix LABoratory’) is a software package and programming language that implements matrix manipulation/linear algebra, numerical methods, and other tasks engineers will often want to accomplish. Many of the core concepts of programming in Matlab, such as for loops or if statements , are the same as programming in other languages like Java, C++, or Python. However, Matlab differs from many common programming languages in the myriad functions and toolkits included in the language, its slightly different syntax, and the fact that it is interpreted (versus compiled). Matlab was chosen for this class primarily because of its wide use in industry and academia, its elaborate matrix manipulation functionality, tools for efficient graphing/plotting, implementation of numerical algorithms, and specialized analysis toolkits. 1.1 Getting Matlab • Buy the Educational Version : http://www.mathworks.com/academia/student_version/ It costs $99, but is worth it. After purchasing the software, you can either download the installa tion files or have a DVD mailed to you. As a note, Mathworks generally won’t deliver the product to PO Boxes, such as your campus mailbox. You can have it delivered to my office to get around that: Your Name, 98 Brett Road, Room B110, Piscataway, NJ 08854 . • Use it in the Computer Labs : The DSV and EIT labs in the Engineering Building have Matlab. You can find the labs’ hours here: http://ecs.rutgers.edu/ . Matlab is also available in ARC lab and other labs on campus; you can the operating hours here: http://www.nbcs.rutgers.edu/ccf/main/schedules/ • Access Matlab remotely from your own computer : You can access Matlab from your own computer in the dorm remotely. I’ll give example instructions for Windows users. First, download and install an X Windows client such as Xming ( http://sourceforge.net/projects/xming/ ). Open Xming. Then, download an SSH client such as Putty ( http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html ). Open Putty, and enter engsoft.rutgers.edu as the hostname. (and make sure that port 22 and SSH are chosen). Then, on the bottomlefthand side, click the + next to SSH, click on ‘X11’, and check the ‘Enable X11 forwarding’ box. On the toplefthand side, click on session again, and choose ‘Open.’ A black window should open and prompt you for your username and password of your ENGINEERING account. Then, you’ll be at a command prompt. Type ‘matlab’, hit enter, and it should open. • Use An Open Source Matlab Alternative such as Octave or Scilab....
