Master Object-Oriented Programming (OOP) in MATLAB

Whether you are building complex engineering models, developing custom UI components, or managing massive datasets, Object-Oriented Programming (OOP) in MATLAB allows you to write cleaner, more scalable, and highly reusable code.

Transitioning from traditional procedural scripting to an object-oriented approach is a critical step for data scientists and engineers looking to build professional-grade software. Explore our curated list of the best MATLAB OOP courses designed to take you from basic scripts to advanced software architecture.

Why Learn Object-Oriented Design in MATLAB?

Most engineers learn MATLAB as a scripting language. Adopting OOP principles unlocks advanced capabilities for your projects:

  • Code Reusability: Define classes and methods once, and reuse them across multiple projects without rewriting logic.

  • Data Encapsulation: Protect your variables from accidental overwriting by hiding internal states and exposing only necessary methods.

  • Handle vs. Value Classes: Master MATLAB’s unique class systems to optimize memory management when passing large data structures.

  • Simplified Maintenance: Break down monolithic scripts into modular, easy-to-debug objects.

What You Will Learn in a Top MATLAB OOP Course

A comprehensive MATLAB object-oriented programming course should cover both foundational concepts and MATLAB-specific syntax. Look for syllabuses that include:

  1. Class Definition & Syntax: How to write classdef blocks, define properties, and build constructors.

  2. Methods and Functions: Creating ordinary methods, static methods, and property access methods (getters and setters).

  3. Inheritance & Subclassing: Building hierarchical relationships using superclasses to share common behaviors.

  4. Events and Listeners: Programming interactive applications where objects react to state changes.

  5. Advanced Memory Management: Understanding how handle classes pass by reference while value classes pass by value.

Is Object-Oriented Programming useful in MATLAB? Yes. While MATLAB is famous for matrix operations and procedural scripting, OOP is essential for managing complex applications, building graphical user interfaces (App Designer), and collaborating on large codebases.

What is the difference between Handle and Value classes in MATLAB? Value classes behave like standard MATLAB variables—when you copy them, the data is duplicated. Handle classes behave like pointers or references; copying a handle object simply copies the reference to the original data, which is highly efficient for large datasets or UI components.

Do I need prior OOP experience (like C++ or Python) to learn MATLAB OOP? No prior OOP experience is required. However, you should have a solid grasp of basic MATLAB programming, including functions, loops, and data structures (cells and structs), before diving into classes and objects.

Introduction to Object Oriented Programming
Module 1: Introduction to Object-Oriented Programming (OOP) Transitioning from standard procedural scripting to Object-Oriented Programming is a fundamental shift in how you think about and design software. In traditional programming, data (variables) and behavior (functions) are treated as separate entities. In OOP, you bundle them together into cohesive, self-contained "objects." The "Feel" of OOP: Modeling Real Engineering Systems OOP allows your code to mirror physical architecture. For example, instead of passing massive arrays of voltages and temperatures through dozens of separate, disconnected functions, you can create a BatteryManagementSystem object. This object internally holds its own state of charge and chemistry logic, and it possesses specific, built-in behaviors like charge() or discharge(). Similarly, instead of managing individual wheel speeds in a messy loop, you can build a single RobotController object that handles the entire PID algorithm internally. It is programming with smart, modular building blocks. The Advantages of the OOP Paradigm: Modularity and Organization: Code is divided into logical, self-contained units. This eliminates the "spaghetti code" that often plagues long procedural scripts and makes navigating your workspace intuitive. Ultimate Reusability: You write the blueprint (the class) only once. From that single blueprint, you can generate hundreds of distinct, independent objects without rewriting a single line of code. Maintainability and Safety: Because objects manage and protect their own internal data (encapsulation), bugs are isolated to specific components. You can update or fix one subsystem without risking the collapse of your entire application. Scalable Complexity: OOP is the industry standard for a reason. It is the most effective way to architect massive, reliable engineering tools and applications without drowning in variable entanglement and global workspace conflicts.

Build in class behaviour in MATLAB
Module 2: Leveraging Built-In MATLAB Class Functionality One of the most powerful aspects of Object-Oriented Programming in MATLAB is the ability to seamlessly integrate your custom classes into MATLAB’s native ecosystem. This module focuses on utilizing MATLAB's built-in tools and behaviors to make your custom objects act and feel exactly like native data types, making your code significantly more intuitive for yourself and end-users. Instead of fighting against the software's default behaviors, you will learn how to hook into MATLAB's underlying architecture to create smart, responsive objects. Key Concepts Covered in This Module: Operator Overloading: Learn how to redefine standard MATLAB operators (like +, -, ==) and core functions (like disp(), plot(), or length()) to work directly with your custom objects. For instance, you can overload the plot() function so that simply typing plot(myBMS) automatically generates a customized graph of your Battery Management System's charging state, rather than throwing an error. Property Validation and Attributes: Discover how to utilize MATLAB's built-in property validation block (e.g., mustBeNumeric, mustBePositive) and access modifiers (SetAccess, GetAccess). This allows you to enforce strict data integrity without writing verbose, repetitive error-checking if/else statements in your methods. MATLAB Mixin Classes: Explore how to inherit from MATLAB’s powerful built-in superclasses. By subclassing mixins like matlab.mixin.SetGet or matlab.mixin.Copyable, your custom classes instantly inherit advanced, out-of-the-box functionalities—such as deep copying capabilities or standard set and get syntaxes—saving you hours of manual coding. Object Arrays and Indexing: Understand how MATLAB handles arrays of objects natively, and learn how to customize array indexing so your objects behave predictably when concatenated or iterated through in a loop.

Argument Validation of class in MATALB
Module 3: Argument Validation for Classes and Objects When building professional-grade software, assuming that another script—or another user—will always provide the exact correct data type is a recipe for disaster. This module dives into argument validation: the architectural practice of strictly defining, filtering, and enforcing what inputs your classes and methods are allowed to accept. By catching bad data before it is allowed to enter your object's internal logic, you prevent catastrophic downstream crashes and ensure your software remains robust, predictable, and structurally sound. Key Concepts Covered in This Module: Type and Size Enforcement: Learn how to lock down method inputs and class constructors so they only accept specific dimensions (e.g., a 1x3 vector) and data classes (e.g., purely numeric values or specific object types). Physical Constraint Validation: Discover how to implement validation blocks that mirror real-world engineering limits. For example, you can enforce that a motor speed command never exceeds its physical maximum RPM, or that a battery capacity input is strictly a positive number. Optional Inputs and Default Values: Design flexible, user-friendly class constructors and methods that can intelligently handle missing arguments by automatically assigning safe, predefined default parameters. Professional Error Handling: Move away from cryptic, red MATLAB console errors. You will learn how to structure validations so that when a user inputs incorrect data, the class rejects it gracefully and returns a clear, actionable error message guiding them to the correct format.

Introduction to the concept of superclass and subclass
Module 4: Inheritance and Hierarchical Class Design In complex engineering software, many components share core characteristics but differ in their specific, real-world implementations. Inheritance is the Object-Oriented mechanism that solves this by allowing you to define a general "parent" class (the superclass) and then create specialized "child" classes (subclasses) that automatically adopt all the properties and methods of the parent. This drastically reduces redundant code and creates a clean, logical taxonomy for your software. The "Feel" of Inheritance: Modeling System Variations Imagine you are building a simulation for various hybrid electric vehicle configurations. Instead of writing completely separate scripts from scratch for each layout, you can create a single base HybridVehicle class that handles universal physics—like chassis weight, aerodynamic drag, and basic battery pack management. You can then create specialized subclasses for specific configurations, such as a P3_Architecture or P4_Architecture. These subclasses automatically inherit all the universal physics from the parent class, meaning you only need to write new code for their unique motor placement and transmission logic. Key Concepts Covered in This Module: Superclasses and Subclasses: Learn the MATLAB syntax (using the < operator) to establish a parent-child relationship between classes, passing down properties and methods securely. Method Overriding: Discover how a subclass can inherit a standard method from its parent but intentionally "override" it with custom logic. For example, a PIDController subclass might override a generic calculateOutput() method to implement a specific proportional-integral-derivative algorithm instead of a simple on-off control. Abstract Classes: Master the use of abstract classes to create strict architectural templates. An abstract class acts as a blueprint that cannot be instantiated on its own; it exists solely to force any future subclasses to implement specific, required methods, ensuring absolute consistency across large projects. Constructor Chaining: Understand how to properly initialize inherited objects by calling the parent class's constructor from within the child class, ensuring all foundational data is correctly established before the specialized logic takes over.

Types of class attributes in MATLAB object oriented programming
Module 5: Core Syntax and Class Definition (classdef) This module bridges the gap between theoretical architecture and executable code. Here, we break down the fundamental syntax of Object-Oriented Programming in MATLAB, exploring exactly how a class is constructed from the ground up using the classdef keyword. Practical Implementation: Code-Driven Learning Theory is only useful when you can compile and run it. In this section, we step directly into the MATLAB editor for hands-on demonstration. We will take a practical engineering concept—such as defining a digital sensor or a motor controller—and write the complete class definition line-by-line. You will see exactly how to structure the .m file, define the blueprint, and ultimately bring the object to life within your MATLAB workspace. Key Concepts Covered in This Module: The classdef Structure: Master the anatomy of a MATLAB class file. You will learn how to properly organize the classdef, properties, and methods blocks so that the MATLAB compiler reads and executes your architecture flawlessly. Defining Properties and Methods: Learn how to declare the internal data variables (properties) that define your object's state, and the functions (methods) that dictate its behavior, keeping them logically bound together. The Constructor Method: Dive into the most critical method of any class: the constructor. You will learn how to write the initialization logic that dictates exactly what happens the moment a new object is created in the workspace. Object Instantiation and Workspace Interaction: Move beyond writing the class file to actually using it. We will demonstrate how to instantiate multiple independent objects from your single class blueprint, interact with their properties, and trigger their methods directly from the command window or a separate script.

Creating package and class folder for product design
Module 6: Software Packaging and Product Development Writing exceptional Object-Oriented code is only half the battle; the final step is delivering that code as a professional, user-ready product. This module serves as the capstone of the curriculum, focusing on how to transition your architecture from a collection of local .m files into a fully functioning, distributable software package. Whether you are deploying an internal engineering tool for your team or releasing a commercial toolbox to the public, this section covers the exact file structures and deployment strategies required to productize your work. Key Concepts Covered in This Module: Namespace Management (+ Package Folders): Learn how to utilize MATLAB's + folder structure to create custom namespaces. This critical practice isolates your code, preventing your class names from colliding with built-in MATLAB functions or third-party toolboxes (e.g., calling myproduct.PIDController instead of a generic PIDController). Class Organization (@ Folders): Discover how to cleanly manage massive classes by breaking them down into @ directories. This allows you to store each method in its own separate file, making your project highly maintainable rather than forcing you to navigate a single, monolithic thousand-line script. Access Control and Hidden Architectures: Implement advanced encapsulation techniques to protect your proprietary backend logic. You will learn how to structure your packages so that end-users only interact with a clean, public-facing API while the internal mechanics remain hidden and secure. Toolbox Packaging and Distribution: Walk through the end-to-end process of compiling your entire class architecture, dependencies, and built-in help documentation into a single, installable MATLAB Toolbox (.mltbx). You will learn how to deliver a seamless installation experience for your end-users.
