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.

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

2. Include the lema.h file in your project.

   #include "lema.h"
   

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

Example Usage

Creating a Matrix

#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

#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

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

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

    Matrix result = a.Multiply(&b);

    result.Print("A x B");

    return 0;
}
