disp函数的介绍


disp(

X

)

displays the value of variable

X

without printing the variable name. Another way to display a variable is to type its name, which displays a leading ”

X =

” before the value.

If a variable contains an empty array,

disp

returns without displaying anything

主要学习disp函数及其基本操作

示例1：


Create a variable with numbers and another variable with text.

输入：
A = [15 150];
S = 'Hello World.';
disp(A)
disp(S)

输出：
15   150
Hello World.

示例2：


Display a matrix and label the columns as

Corn

,

Oats

, and

Hay

.

输入：
X = rand(5,3);
disp('     Corn      Oats      Hay')
disp(X)


输出：
    Corn      Oats      Hay
    0.8147    0.0975    0.1576
    0.9058    0.2785    0.9706
    0.1270    0.5469    0.9572
    0.9134    0.9575    0.4854
    0.6324    0.9649    0.8003

示例3




Display a link to a Web page by including HTML hyperlink code as input to

disp

. For example, display a link to the MathWorks® Web site.

输入：
X = '<a href = "http://www.mathworks.com">MathWorks Web Site</a>';
disp(X)


输出：
MathWorks Web Site

示例4




Display Multiple Variables on Same Line

输入：
name = 'Alice';   
age = 12;
X = [name,' will be ',num2str(age),' this year.'];
disp(X)


输出：
Alice will be 12 this year.

输入：
name = 'Alice';   
age = 12;
X = sprintf('%s will be %d this year.',name,age);
disp(X)


输出：
Alice will be 12 this year.

输入：
name = 'Alice';   
age = 12;
fprintf('%s will be %d this year.\n',name,age)


输出：
Alice will be 12 this year.

总结：

以上就是今天要讲的内容，本文仅仅简单介绍了字典的使用，并解决了二个数求和问题
