## Overview

NumXX is a header-only C++17 numerical-array library inspired by NumPy. A typical user creates an NArray, applies element-wise or aggregate operations, and consumes the resulting arrays or values. The graph preserves documented capabilities including slicing, matrix/vector operations, functional math, random generation, FFT, and file handling. Some subsystem links reflect README capabilities and tree paths; unsampled implementation details are not expanded into inferred call chains.

Main entry points: [`NumXX/Containers/NArray.hpp`](https://github.com/abdallahsoliman00/numxx/blob/main/NumXX/Containers/NArray.hpp) (NArray), [`NumXX/Core/ArrayCreation.hpp`](https://github.com/abdallahsoliman00/numxx/blob/main/NumXX/Core/ArrayCreation.hpp) (Array creation), [`NumXX/Containers/Matrix.hpp`](https://github.com/abdallahsoliman00/numxx/blob/main/NumXX/Containers/Matrix.hpp) (Matrix), [`NumXX/Random.hpp`](https://github.com/abdallahsoliman00/numxx/blob/main/NumXX/Random.hpp) (Random generation)
