Matrix Operations in Java

This project implements a modular Java program to perform various matrix operations such as:

• Addition and Subtraction
• Multiplication
• Transpose
• Rank Calculation
• Determinant
• Inverse

It follows an object-oriented approach and clean package structure for better maintainability.

🧠 How It Works

• All operations implement the MatrixOperations interface.
• The Matrix class handles input, validation, and common matrix utilities.
• Each operation class (like Add_Sub, Inverse, etc.) contains logic specific to that operation.
• MatrixDriver is the main class that takes user input and dispatches the selected operation.

🛠 How to Compile and Run

1. Using .bat script (Recommended for Windows)

Simply run:

runMatrixProject.bat

This script:

• Compiles all Java files from src/
• Stores compiled .class files in out/
• Runs the MatrixDriver class from out/

2. Manual Compilation (Optional)

cd src
javac -d ../out matrix/**/*.java operation/*.java exceptions/*.java driver/*.java
java -cp ../out driver.MatrixDriver

📋 Features

• Clean, modular codebase
• Follows best OOP practices
• Handles square matrix validation via custom exception
• Uses Java 17+ features (like enhanced switch)

---

🧪 Requirements

• Java JDK 17 or above
• Any terminal or IDE (VS Code, IntelliJ, etc.)

---

🧱 Future Enhancements

• Support for file input/output
• GUI using JavaFX or Swing
• More matrix operations (e.g., eigenvalues, LU decomposition)
