Syntax
Description
Examples
Display Variable Values
Create a variable with numbers and another variable with text.
A = [15 150];
S = 'Hello World.';
Display the value of each variable.
disp(A)
15 150
disp(S)
Hello World.
Display Matrix with Column Labels
Display a matrix and label the columns as Corn
, Oats
, and Hay
.
X = rand(5,3);
disp(' Corn Oats Hay')
Corn Oats Hay
disp(X)
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
Display Hyperlink in Command Window
Display a link to a Web page by including HTML hyperlink
code as input to disp
. For example, display
a link to the bat365® Web site.
X = '<a href = "">bat365 Web Site</a>';
disp(X)
Display Multiple Variables on Same Line
Here are three ways to display multiple variable values on the same line in the Command Window.
Concatenate multiple character vectors together using the []
operator. Convert any numeric values to characters using the num2str
function. Use disp
to display the result.
name = 'Alice'; age = 12; X = [name,' will be ',num2str(age),' this year.']; disp(X)
Alice will be 12 this year.
Use sprintf
to create text, and then display it with disp
.
name = 'Alice'; age = 12; X = sprintf('%s will be %d this year.',name,age); disp(X)
Alice will be 12 this year.
Use fprintf
to directly display the text without creating a variable. However, to terminate the display properly, you must end the text with the newline (\n
) metacharacter.
name = 'Alice'; age = 12; fprintf('%s will be %d this year.\n',name,age);
Alice will be 12 this year.
Input Arguments
X
— Input array
array
Input array.
To display more than one array, you can use concatenation or
the sprintf
or fprintf
functions
as shown in the example, Display Multiple Variables on Same Line.
