Octave Input and Output

In this tutorial, we will learn about Octave input and output statements.

Input

The input function can prompt the user for a value and store the result in a variable.

For example, the statement prints the prompt and stores the user input in a variable num.

num = input (“Enter the number: “)

>> a = input(‘Enter number=’);
Enter number=47
>> a
a = 47
>> disp(a)
47

Output

To print the value of a variable, we can use the disp function.
For example, the following statement will output the value of the variable num.

We can use the following output statements in Octave:

• disp
• printf
• fprintf

We can use the format specifiers in the output statement, for example in the fprintf statement.

Example to use the display function:

disp (num)

Example to use the fprintf function:

fprintf(‘%d’,num);

>> a = 25;
>> a
a = 25
>> disp(a)
25
>> fprintf(‘Value of a = %d\n’,a);
Value of a = 25
