Write a script file on Octave based on the following criteria. The users should be able to add a value for ‘x’ and then see the output ‘y’ when the program is run.

Homework Help: Questions and Answers: Part a) Write a script file on Octave based on the following criteria. The users should be able to add a value for ‘x’ and then see the output ‘y’ when the program is run. Name the program as Question4.

If x>100, then y=10x

If 100 ≥ x ≥ 0, then y=x/10

If x<0, then y=abs(x)

Part b) Test your program you created in part a for x=200, x=10, and x=-10.

Answer

Part a) Writing the Octave Script

Here’s the script file named Question4.m that implements the given criteria.

% Question4.m % This script calculates the value of y based on the input value of x.

% Prompt the user to enter a value for x x = input('Enter a value for x: ');

% Calculate the value of y based on the value of x if x > 100 y = 10 * x; elseif x >= 0 && x <= 100 y = x / 10; else y = abs(x); end

% Display the result fprintf('The value of y is: %f\n', y);

Explanation:

Input: The script prompts the user to enter a value for x.

Conditions:

If x > 100, then y is calculated as 10 * x.

If 100 ≥ x ≥ 0, then y is calculated as x / 10.

If x < 0, then y is calculated as abs(x).

Output: The script then displays the value of y.

Part b) Testing the Program

To test the program for x = 200, x = 10, and x = -10, you can run the script in Octave with these inputs. Below are the expected outputs:

Test 1: x = 200

Enter a value for x: 200 The value of y is: 2000.000000

Explanation: Since x > 100, y = 10 * 200 = 2000.

Test 2: x = 10

Enter a value for x: 10 The value of y is: 1.000000

Explanation: Since 100 ≥ x ≥ 0, y = 10 / 10 = 1.

Test 3: x = -10

Enter a value for x: -10 The value of y is: 10.000000
