Matrices and Magic Squares
The best way for you to get started with MATLAB is to learn how to handle
matrices. This section shows you how to do that. In MATLAB, a matrix is a
rectangular array of numbers. Special meaning is sometimes attached to
1-by-1 matrices, which are scalars, and to matrices with only one row or
column, which are vectors. MATLAB has other ways of storing both numeric
and nonnumeric data, but in the beginning, it is usually best to think of
everything as a matrix. The operations in MATLAB are designed to be as
natural as possible. Where other programming languages work with numbers
one at a time, MATLAB allows you to work with entire matrices quickly and
easily.

第五章

Expressions
Like most other programming languages, MATLAB provides mathematical
expressions, but unlike most programming languages, these expressions
involve entire matrices. The building blocks of expressions are
•Variables
•Numbers
•Operators
•Functions
Variables
MATLAB does not require any type declarations or dimension statements.
When MATLAB encounters a new variable name, it automatically creates the
variable and allocates the appropriate amount of storage. If the variable
already exists, MATLAB changes its contents and, if necessary, allocates new
storage. For example
num_students = 25
creates a 1-by-1 matrix named num_students and stores the value 25 in its
single element.
Variable names consist of a letter, followed by any number of letters, digits, or
underscores. MATLAB uses only the first 31 characters of a variable name.
MATLAB is case sensitive; it distinguishes between uppercase and lowercase
letters. A and a are not the same variable. To view the matrix assigned to any
variable, simply enter the variable name.

第六章

Working with Matrices
This section introduces you to other ways of creating matrices.
Generating Matrices
MATLAB provides four functions that generate basic matrices:
zeros all zeros
ones all ones
rand uniformly distributed random elements
randn normally distributed random elements

第七章

The Command Window
So far, you have been using the MATLAB command line, typing commands and expressions, and seeing the results printed in the command window. This  section describes a few ways of altering the appearance of the command window. If your system allows you to select the command window font or
typeface, we recommend you use a fixed width font, such as Fixedsys or Courier, to provide proper spacing.

第八章

Graphics
MATLAB has extensive facilities for displaying vectors and matrices as graphs,as well as annotating and printing these graphs. This section describes a few
of the most important graphics functions and provides examples of sometypical applications.

第九章：

Help and Online Documentation
There are several different ways to access online information about MATLAB
functions.
•The help command
•The help window
•The MATLAB Help Desk
•Online reference pages
•Link to The MathWorks, Inc.

第十章

The MATLAB Environment
The MATLAB environment includes both the set of variables built up during a
MATLAB session and the set of disk files containing programs and data that
persist between sessions.

第十一章

More About Matrices and Arrays
This sections shows you more about working with matrices and arrays,
focusing on
•Linear Algebra
•Arrays
•Multivariate Data

第十二章

Flow Control
MATLAB has five flow control constructs:
•if statements
•switch statements
•for loops
•while loops
•break statements

第十三章：Other Data Structures
This section introduces you to some other data structures in MATLAB
including:
•Multidimensional arrays
•Cell arrays
•Characters and text
•Structures

第十四章：Scripts and Functions
MATLAB is a powerful programming language as well as an interactive
computational environment. Files that contain code in the MATLAB languageare called M-files. You create M-files using a text editor, then use them as youwould any other MATLAB function or command.

第十五章：Handle Graphics
MATLAB provides a set of low-level functions that allows you to create andmanipulate lines, surfaces, and other graphics objects. This system is called Handle Graphics®.

第十六章：Learning More
To see more MATLAB examples, selectExamples andDemos under the menu,
or type
demo
at the MATLAB prompt.  From the menu displayed, run the demos that
interest you, and follow the instructions on the screen.

platform.
•Using MATLAB provides in depth material on the MATLAB language,
working environment, and mathematical topics.
•Using MATLAB Graphics describes how to use MATLAB’s graphics and visu-
alization tools.
