Beginner-Friendly Step By Step MATLAB Tutorials You Can Follow Today

If you’ve been searching for step by step MATLAB tutorials, get ready—because this guide will take you from absolute beginner to confident user in a smooth, conversational, and thoroughly explained way.

My goal here is to make MATLAB feel easy, logical, and fun, even if you’re learning it for the first time.

1. Introduction to MATLAB

MATLAB (short for Matrix Laboratory) is a high-level programming language designed mainly for:

• Engineering
  
• Mathematics
  
• Data science
  
• Machine learning
  
• Simulation
  
• Signal processing
  
• Robotics
  
• Academic research

What makes MATLAB special—especially for beginners—is its simplicity. Unlike many programming languages where you need multiple steps just to display a message, MATLAB lets you type and instantly see results.

Think of MATLAB as a calculator on steroids—fast, visual, and packed with ready-made tools.

2. Understanding the MATLAB Interface (Your Control Room)

Before writing code, let’s understand where you’ll be working. When MATLAB opens, you’ll see:

a) Command Window

This is where you enter quick commands that run immediately. Perfect for testing ideas.

b) Workspace

Shows all the variables you’ve created. Great for tracking data.

c) Command History

Displays the commands you previously ran.

d) Current Folder

Shows the files in your working directory.

e) Editor

Where you write longer scripts and functions for saved programs.

Understanding this layout makes your workflow smoother because you know exactly where things happen.

3. Step 1: Running Your First Commands

Let’s start with something simple so you get comfortable.

Type this in the Command Window:

2 + 3

You’ll instantly see:

ans = 5

Now try:

sqrt(25)

Which returns:

5

With just a command or two, you’re already using MATLAB as a math tool.

4. Step 2: Creating and Using Variables

Variables help you store values. MATLAB makes this extremely easy.

Examples:

x = 10

y = 20

z = x + y

MATLAB automatically stores the value of z in the Workspace as:

z = 30

Important:

MATLAB is case-sensitive.
Value and value are not the same variable.

5. Step 3: Working with Arrays and Matrices

MATLAB is a matrix-based language, so let’s get comfortable with arrays.

Row vector:

r = [1 2 3 4]

Column vector:

c = [1; 2; 3; 4]

Matrix:

A = [1 2; 3 4]

Matrix Addition:

B = [5 6; 7 8]

C = A + B

Matrix Multiplication:

D = A * B

If you’re studying linear algebra, this is where MATLAB becomes incredibly powerful.

6. Step 4: Creating MATLAB Scripts (Your First Program)

If you want to store multiple lines of code, use a script.

Steps:

1. Go to Home → New Script
   
2. Type the following:

a = 5;

b = 8;

c = a + b;

disp([‘The result is: ‘, num2str(c)]);

3. Save it as myFirstScript.m
   
4. Click Run

Output:

The result is: 13

Scripts are the foundation of longer MATLAB programs.

7. Step 5: Writing Functions (Reusable Code)

Functions allow you to reuse logic. You write them in separate files.

Try this:

function result = squareNumber(n)

    result = n^2;

end

Save this file as squareNumber.m.

Now run:

squareNumber(7)

Output:

49

You just wrote your first MATLAB function!

8. Step 6: Conditionals (Making Decisions in Code)

Conditional statements help your code make choices.

Example:

x = 15;

if x > 10

    disp(‘The number is greater than 10’);

elseif x == 10

    disp(‘The number is exactly 10’);

else

    disp(‘The number is less than 10’);

end

This is extremely useful in logical operations and simulations.

9. Step 7: Loops (Repeating Tasks Automatically)

FOR Loop

Runs a fixed number of times.

for i = 1:5

    disp([‘Iteration: ‘, num2str(i)]);

end

WHILE Loop

Runs until a condition is met.

x = 1;

while x <= 5

    disp([‘Value: ‘, num2str(x)]);

    x = x + 1;

end

Loops are essential when working with big datasets or simulations.

10. Step 8: Plotting Graphs (MATLAB’s Superpower)

This is where MATLAB shines visually.

Plot a simple graph:

x = 0:0.1:10;

y = sin(x);

plot(x, y);

title(‘Sine Wave’);

xlabel(‘x’);

ylabel(‘sin(x)’);

You’ll instantly see a smooth sine curve.
No complicated settings, no graphics libraries—just beautiful plots.

11. Step 9: Importing and Exporting Data

MATLAB makes reading files simple.

Import CSV file:

data = readtable(‘mydata.csv’);

Preview data:

head(data)

Export data:

writetable(data, ‘output.csv’);

This is incredibly useful for machine learning and data analysis.

12. Step 10: Debugging and Troubleshooting

MATLAB gives helpful error messages.
But here are common mistakes to avoid:

1. Missing parentheses

plot x, y   → WRONG

plot(x, y)  → RIGHT

2. Using the wrong file name

Function file name must match the function name.

3. Mixing row and column vectors

Always check your dimensions.

Debugging tools like breakpoints, the Editor, and the Command Window make error-fixing easy.
