NumCpp
NumCpp est un framework C++ et une bibliothèque de calcul numérique qui fournit une boîte à outils pour la gestion de tableaux multidimensionnels et des routines mathématiques. Il fonctionne comme une implémentation C++ de l'écosystème NumPy, offrant un framework de calcul scientifique pour gérer des tenseurs et effectuer des équations algébriques complexes.
Le projet permet une manipulation de tableaux haute performance dans un environnement C++ sans dépendre d'un runtime Python. Il se distingue en fournissant une interface similaire à NumPy pour exécuter de l'algèbre linéaire, gérer des structures de données multidimensionnelles et effectuer des traitements numériques.
La bibliothèque couvre un large éventail de capacités, incluant les opérations algébriques matricielles, la gestion de la géométrie des tableaux via le slicing et le reshaping, et la génération de distributions aléatoires. Elle inclut également des outils pour l'analyse de jeux de données, les statistiques sur les tableaux, et l'import/export de données numériques via des formats binaires et texte.
