# LeMA : Matrices simply

LeMA (short for "Leto Matrix") is a lightweight C++ header-only library designed to simplify matrix manipulation.
LeMA will eventually be used for graphical and machine learning usage in my other projects.

## Features

- **Lightweight**: Just a single header file.
- **Easy to Use**: Intuitive functions.
- **Somewhat complete**: Supports addition, subtraction, multiplication, and more.
- **Ready to Integrate**: Designed to work seamlessly with C++ code.

## Getting Started

### Installation

1. Clone or download the repository.
   ```bash
   git clone https://git.letonet.fr/gitea_admin/lema.git
   ```

2. Include the `lema.h` file in your project.
   ```cpp
   #include "lema.h"
   ```

That's it! You're ready to use Lema.

### Example Usage

#### Creating a Matrix

```cpp
#include "lema.h"
#include <iostream>

int main() {
    Matrix mat(3, 2); // Create a 3 rows, 2 columns matrix
    mat.Print("Weights"); // LeMA can print matrices in terminal for easy debugging
    return 0;
}
```

#### Matrix Addition

```cpp
#include "lema.h"
#include <iostream>

int main() {
    Matrix a(2,2);
    Matrix b(2,2);

    a.Set(2.0F); // Fill both matrices
    b.Set(3.0F);

    a.Add(&b);

    a.Print("A + B");
    return 0;
}
```

#### Matrix Multiplication

```cpp
#include "lema.h"
#include <iostream>

int main() {
    Lema::Matrix<int> mat1(2, 2, {1, 2, 3, 4});
    Lema::Matrix<int> mat2(2, 2, {1, 0, 0, 1});

    auto result = mat1 * mat2;

    std::cout << "Result of multiplication:\n";
    result.print();
    return 0;
}
```
