  1. MATLAB WORKSHOP • FOR EE 327 • MWF 8:00-850 AM • August 26-30, 2002 Dr. Ali A. Jalali

  2. ABOUT WORKSHOP Mainly this workshop is designed for EE 327, Signals and Systems 1 course. But it could be used by any other faculty and students who are interested to learn MATLAB

  3. ABOUT WORKSHOP This workshop is available as a supplement to the textbook Contemporary Linear Systems Using MATLAB by Robert D. Strum and Donald E. Kirk. This is the main textbook for EE 327 in fall 2002. The workshop covers basic MATLAB commands that are used in introductory signals and systems analysis. It is meant to serve as a quick way to learn MATLAB and a quick reference to the commands that are used in this textbook.

  4. ABOUT WORKSHOP In this workshop you will learn a few of the basic functions of MATLAB. First we will start working with basic numbers, formats, demos, mathematical functions, setting variables, matrices and generating plots by using the plot functions. Brief overview of how to generate scripts in MATLAB called M-files.

  5. ABOUT WORKSHOP The workshop is designed for students using either the professional version of MATLAB with the Control Systems Toolbox and the Signal Processing Toolbox, or using the Student Edition of MATLAB. For latest version of MATLAB at the time and more information on MATLAB, contact The Mathworks, Inc. www.mathworks.com

  9. MATLAB Introduction MATLAB is both computer programming language and software environment for using that language effectively. MATLAB is matrix-oriented, so what would take several statements in C or Fortran can usually be accomplished in just a few lines using MATLAB's built-in matrix and vector operations

  10. MATLAB Introduction FORTRAN: real*8 A(10,10), B(10,10), C(10,10)    do i=1,10    do j=1,10        C(i,j) = A(i,j) + B(i,j) 10 continue 20 continue MATLAB: C = A + B

  11. MATLAB Introduction MATLAB is available for MS Windows, Macintosh personal computer, Unix and other operating systems.

  12. MATLAB Introduction MATLAB, which stands for MATrix LABoratory, is a powerful, general-purpose system or environment for doing mathematics, scientific and engireeng calculations.

  13. MATLAB Introduction MATLAB is a "High-Performance Numeric Computation and Visualization Software" package.

  14. MATLAB Introduction MATLAB is an interactive system whose basic data is a matrix that does not require dimensioning.

  15. MATLAB Introduction MATLAB supports many types of graph and surface plots: • line plots (x vs. y), • filled plots, • bar charts, • pie charts, • parametric plots, • polar plots, • contour plots, • density plots, • log axis plots, • surface plots, • parametric plots in 3 dimensions and spherical plots.

  16. MATLAB Introduction • MATLAB has a number of add-on software modules, called toolbox, that perform more specialized computations. Signal & Image Processing Signal Processing- Image ProcessingCommunications - System Identification - Wavelet Filter Design Control Design  Control System - Fuzzy Logic - Robust Control - µ-Analysis and Synthesis - LMI Control  - Model Predictive ControlModel-Based Calibration More than 60 toolboxes!

  17. MATLAB Introduction • In Windows systems MATLAB is started by double-clicking the mouse on the appropriate icon.
