all operating systems, your MATLAB & Simulink Student Version CD must be in your CD-ROM drive to start MATLAB (Microsoft Windows) Double-click the MATLAB icon on your desktop... purchase add-on products and documentation 1-9 1 Introducing the MATLAB & Simulink Student Version MATLAB Central — File Exchange/Newsgroup Access At www.mathworks.com/matlabcentral, you can access the MATLAB Usenet newsgroup (comp.soft-sys .matlab) as well as an extensive library of user-contributed files called the MATLAB Central File Exchange MATLAB Central is also home to the Link Exchange where you can... default definitions, or any MATLAB expressions that you want executed every time MATLAB is invoked, create a file named startup.m in the $MATLAB\ toolbox\local folder, where $MATLAB is the name of your MATLAB installation folder Every time you start MATLAB, it executes the commands in the startup.m file 12 Perform any additional configuration by typing the appropriate command at the MATLAB command prompt... Professional Versions (p 1-11) Product differences 1 Introducing the MATLAB & Simulink Student Version Quick Start If you need help installing the software, see Chapter 2, “Installing the MATLAB & Simulink Student Version.” At the heart of MATLAB is a programming language you must learn before you can fully exploit its power You can learn the basics of MATLAB quickly, and mastery comes shortly after You will... installation is complete, verify the installation by starting MATLAB and running one of the demo programs To start MATLAB, double-click on the MATLAB icon that the installer creates on your desktop To run the demo programs, select Demos from Help Note The MATLAB & Simulink Student Version CD must be in your CD-ROM drive to start MATLAB 11 Customize any MATLAB environment options, if desired For example, to... desktop (Macintosh OS X) Double-click the MATLAB icon on your desktop (Linux) Enter the matlab command at the command prompt I’m new to MATLAB and want to learn it quickly I want to look at some samples of what you can do with MATLAB 1-6 Start by reading Chapter 3, “Introduction,” through Chapter 6, “Programming,” in this book The most important things to learn are how to enter matrices, how to use... accessing MATLAB Check your desired options and click Finish to complete the installation 10 Verify the installation by starting MATLAB and running one of the demo programs To start MATLAB, double-click on the MATLAB icon that the installer creates on your desktop To run the demo programs, select Demos from Help Note The MATLAB & Simulink Student Version CD must be in your CD-ROM drive to start MATLAB. .. to every other feature of the professional version of MATLAB MATLAB Differences There are a few small differences between the Student Version and the professional version of MATLAB: • The MATLAB prompt in the Student Version is EDU>> • The window title bars include the words • All printouts contain the footer Student Version of MATLAB This footer will always appear in your printouts... in the Student Version • The MATLAB & Simulink Student Version CD must be in your CD-ROM drive to start MATLAB Once MATLAB starts, you can remove the CD Simulink The Student Version contains the complete Simulink product, which is used with MATLAB to model, simulate, and analyze dynamic systems Simulink Differences • Models are limited to 1000 blocks 1-11 1 Introducing the MATLAB & Simulink Student Version... use with the MATLAB & Simulink Student Version Getting Started with MATLAB (p 1-6) Basic steps for using MATLAB Finding Reference Information (p 1-7) How to learn more about MATLAB and related products Troubleshooting (p 1-8) Getting information and reporting problems Other Resources (p 1-9) Additional sources of information for the MATLAB & Simulink Student Version Differences Between the Student and . doc@mathworks.com Documentation error reports ISBN 0- 975 578 7 -09 000 0 Learning MATLAB  COPYRIGHT 1984 - 200 4 by The MathWorks, Inc.
