First MATLAB program - Mini Project: Build & Apply

First MATLAB program

📖 Scenario: You are learning MATLAB, a tool used by engineers and scientists to solve problems with math and data. Let's start by writing your very first MATLAB program.

🎯 Goal: Create a simple MATLAB script that stores a number, doubles it, and then shows the result.

📋 What You'll Learn

Create a variable called number with the value 10

Create a variable called doubled that is twice the value of number

Display the value of doubled using disp

💡 Why This Matters

🌍 Real World

MATLAB is used in engineering and science to quickly test ideas and solve math problems.

💼 Career

Knowing how to write simple MATLAB programs is useful for jobs in data analysis, engineering, and research.

1

Create the initial variable

Create a variable called number and set it to 10.

MATLAB

% Your code here

Need a hint?

Use the equals sign = to assign the value 10 to the variable number.

2

Create a doubled variable

Create a variable called doubled that is number multiplied by 2.

MATLAB

number = 10;
% Your code here

Need a hint?

Multiply number by 2 using the * operator and assign it to doubled.

3

Display the doubled value

Use disp to display the value of doubled.

MATLAB

number = 10;
doubled = number * 2;
% Your code here

Need a hint?

Use disp(doubled); to show the value stored in doubled.

4

Run the program and see the output

Run the program to display the doubled value. The output should be 20.

MATLAB

number = 10;
doubled = number * 2;
disp(doubled); % Run this to see the output

Need a hint?

Run the script. You should see the number 20 printed in the command window.
