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

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

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 Processing
  Communications - System Identification - Wavelet
   Filter Design    
• Control Design 
• Control System - Fuzzy Logic - Robust
  Control - µ-Analysis and Synthesis - LMI Control
   - Model Predictive Control Model-Based
  Calibration
• More than 60 toolboxes!

17
MATLAB Introduction

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