MatLibMini 1.0.1

MatLibMini

MatLibMini is a minimalist and high-performance C# library for working with matrices and vectors. It supports generic numeric types (T : unmanaged, INumber<T>) and SIMD optimizations for common operations such as addition, multiplication, transposition, and more.

🚀 Features

• ✅ Generic numeric type support: int, float, double, etc.
• ✅ SIMD acceleration using System.Numerics.Vector<T>
• ✅ Core matrix operations:
  • Addition (with scalar or another matrix)
  • Multiplication (with scalar or another matrix)
  • Transposition
  • Flattening to vector
• ✅ Vector operations:
  • Dot product
  • Arithmetic operations (add, subtract, multiply)
• ✅ Extension-based modular design
• ✅ No dependencies, easy integration

📦 Installation

You can either clone the repo or add it as a submodule:

git submodule add https://github.com/your-username/MatLibMini.git

Or reference the project directly in your .csproj file:

<ProjectReference Include="MatLibMini/MatLibMini.csproj" />

🧠 Example Usage

Matrix Operations

using MatLibMini;
using MatLibMini.Extensions;

var matA = new Mat<float>(new float[,] {
    {1, 2},
    {3, 4}
});

var matB = new Mat<float>(new float[,] {
    {5, 6},
    {7, 8}
});

matA.Add(matB); // matA += matB

var result = matA.Multiply(matB.Transpose());

Console.WriteLine(result);

Vector Operations

var vec1 = Vec<float>.From(stackalloc float[] {1, 2, 3});
var vec2 = Vec<float>.From(stackalloc float[] {4, 5, 6});

var dot = vec1.Dot(vec2); // 1*4 + 2*5 + 3*6 = 32
Console.WriteLine($"Dot product: {dot}");
