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.
Not a movie: Is not about the 1999 hit movie by the Wachowski transexual sisters.

Getting Started

Installation

Clone or download the repository.

git clone https://git.letonet.fr/leto/lema.git

Include the matrices.h file in your project.
```
#include "matrices.h"
```

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

Example Usage

Creating a Matrix

#include "matrices.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

#include "matrices.h"

int main() {
    Matrix a(2,2);
    a.Set(2.0F); // Fill A with 2s
    
    Matrix b = a;
    Matrix result = a + &b; // Basic operations are possible with pointers

    result.Print("A + B"); // Is full of 4s !
    return 0;
}

Matrix Multiplication

#include "matrices.h"

int main() {
    Matrix a(3, 3);
    Matrix b(3, 1); // Let's multiply by a vector

    Matrix result = a * &b;

    result.Print("A x B"); // Result is a 3 by 1 vector

    return 0;
}
