16 Tutorial Lessons The Basics Here are the lessons in a nutshell: Lesson 1: Launch MATLAB, do some simple calculations, and quit. Key features: Learn to add, multiply, and exponentiate numbers; use trigonometric functions; and control screen output with format . Lesson 2: Create and work with arrays, vectors in particular. Key features: Learn to create, add, and multiply vectors; use sin and sqrt functions with vector arguments; and use linspace to create a vector. Lesson 3: Plot simple graphs. Key features: Learn to plot, label, and print out a circle. Lesson 4: Write and execute a script file. Key features: Learn to write, save, and execute a script file that plots a unit circle. Lesson 5: Write and execute a function file. Key features: Learn to write, save, and execute a function file that plots a circle of any specified radius.
2.1 Lesson 1: A Minimum MATLAB Session 17 2.1 Lesson 1: A Minimum MATLAB Session Goa/: To learn how to log on, invoke MATLAB, do a few trivial calculations, quit MATLAn, and log off. Time Estimates Lesson: 10 minutes Exercises: 30 minutes What you are going to learn • How to do simple arithmetic calculations. The arithmetic operators are • How to assign values to variables. • How to suppress screen output. + * I addition, subtraction, multiplication, division, and exponentiation. • How to control the appearance of floating point numbers on the screen. • How to quit MATLAB. The MATLAB commands/operators used are +, - , *, /, - , sin, cos , log format quit In addition, if you do the exercises, you will learn more about arithmetic operations, exponentiation and logarithms, trigonometric functions, and complex numbers. Method: Log on and launch MATLAB. Once the MATLAB command window is on the screen, you are ready to carry out the first lesson. Some commands and their output are shown in Fig. 2.1. Go ahead and reproduce the results.
