Script files and editor in MATLAB - Mini Project: Build & Apply

Script files and editor

📖 Scenario: You are learning how to use MATLAB script files and the editor to write and run simple programs.

🎯 Goal: Create a MATLAB script file that stores a number, calculates its square, and displays the result using the editor.

📋 What You'll Learn

Create a variable with a specific value

Create a second variable to store the square of the first

Use the MATLAB editor to write the script

Display the result using disp

💡 Why This Matters

🌍 Real World

Using script files in MATLAB helps automate calculations and data processing tasks.

💼 Career

Many engineering and scientific jobs require writing and running MATLAB scripts to analyze data and solve problems.

1

Create a variable in a script

Create a MATLAB script file and write a line that creates a variable called number and sets it to 7.

MATLAB

% Your code here

Need a hint?

Use the assignment operator = to set number to 7.

2

Calculate the square

Add a line to the script that creates a variable called square and sets it to the square of number using the ^ operator.

MATLAB

number = 7;
% Your code here

Need a hint?

Use square = number ^ 2; to calculate the square.

3

Display the result

Add a line to the script that uses disp to display the value of square.

MATLAB

number = 7;
square = number ^ 2;
% Your code here

Need a hint?

Use disp(square); to show the result in the command window.

4

Run the script and see output

Run the script file in the MATLAB editor and observe the output. The output should be 49.

MATLAB

number = 7;
square = number ^ 2;
disp(square);
% Your code here

Need a hint?

Run the script by pressing the Run button or typing the script name in the command window. The output should be 49.
