# Matrix

A toy matrix implementation using modern C++.

## Motivation / Learning Goals

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)](https://github.com/microsoft/GSL) (specifically for safe numeric casts like `narrow_cast`)

* (Optional: Initial experiments with performance considerations in C++.)

## Features

* Basic Matrix class storing `double` values.

* Initialization with dimensions and optional initial data (`std::vector`).

* 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.)*

## Tech Stack / Requirements

* **Language:** C++20

* **Libraries:**

    * [Microsoft Guidelines Support Library (GSL)](https://github.com/microsoft/GSL)

* **Development Environment:** Developed using Visual Studio.
