A toy matrix implementation using modern C++.

This project serves as a personal exercise to learn and deepen my understanding of key C++ concepts. The primary focus was on:

• Object-Oriented Programming (OOP) principles in C++.
• Correctly implementing Operator Overloading for intuitive class usage.
• Utilizing Templates for generic code design.
• Exploring modern C++20 features like Concepts.
• Efficient use of std::vector for underlying data storage.
• Adhering to coding guidelines using the Guidelines Support Library (GSL) (specifically for safe numeric casts like narrow_cast)
• (Optional: Initial experiments with performance considerations in C++.)

• Basic Matrix class storing double values.
• Initialization with dimensions and optional initial data (std::vector<double>).
• Overloaded operator* for:
  • Matrix-Matrix multiplication.
  • Scalar multiplication (Matrix * double).
• size() method to get the total number of elements.
• (Note: Direct public element accessors (get/set methods or operator()) and formatted printing (operator<<) are not currently implemented.)

• Language: C++20
• Libraries:
  • Microsoft Guidelines Support Library (GSL)
• Development Environment: Developed using Visual Studio.
