Starting MATLAB
This book is intended to help you start learning MATLAB. It contains a
number of examples, so you should run MATLAB and follow along.
To run MATLAB on a PC or Mac, double-click on the MATLAB icon. To run
MATLAB on a UNIX system, type matlab at the operating system prompt. To
quit MATLAB at any time, type quit at the MATLAB prompt.
If you feel you need more assistance, type help at the MATLAB prompt, or pull
down on the Help menu on a PC or Mac. We will tell you more about the help
and online documentation facilities later.

第四章

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.
