Variable creation and assignment in MATLAB - Mini Project: Build & Apply

Variable creation and assignment

📖 Scenario: You are working on a simple calculator program that needs to store some numbers before performing operations.

🎯 Goal: Learn how to create variables and assign values to them in MATLAB.

📋 What You'll Learn

Create variables with exact names and values

Assign numeric values to variables

Use MATLAB syntax for variable assignment

Display variable values using disp

💡 Why This Matters

🌍 Real World

Creating and assigning variables is the foundation of any program, allowing you to store and manipulate data.

💼 Career

Understanding variable assignment is essential for all programming jobs, including data analysis, engineering, and software development.

1

Create variables with initial values

Create a variable called a and assign it the value 10. Then create a variable called b and assign it the value 20.

MATLAB

% Your code here

Need a hint?

Use the syntax variableName = value; to assign values.

2

Create a variable for the sum

Create a variable called sum_ab and assign it the value 0.

MATLAB

a = 10;
b = 20;
% Your code here

Need a hint?

Initialize sum_ab with zero before using it.

3

Assign the sum of variables to sum_ab

Assign the sum of variables a and b to the variable sum_ab.

MATLAB

a = 10;
b = 20;
sum_ab = 0;
% Your code here

Need a hint?

Use the plus sign + to add two variables.

4

Display the value of sum_ab

Use the disp function to display the value of the variable sum_ab.

MATLAB

a = 10;
b = 20;
sum_ab = a + b;
% Your code here

Need a hint?

Use disp(variableName) to show the value of a variable.
