Ndarray - manipuler des tableaux multidimensi…

ndarray est une bibliothèque de tableaux multidimensionnels pour Rust qui sert de framework d'algèbre linéaire et d'outil de calcul scientifique. Elle fournit l'infrastructure de base pour créer et manipuler des tableaux n-dimensionnels, fonctionnant à la fois comme un processeur de tableaux parallèle et une boîte à outils pour l'analyse de données numériques.

La bibliothèque se distingue en fournissant un découpage (slicing) et des vues mémoire efficaces, permettant le partage de données sans copie. Elle tire parti de bibliothèques mathématiques backend optimisées pour la multiplication de matrices à haute vitesse et distribue les itérations mathématiques lourdes sur plusieurs threads CPU pour accélérer le traitement.

Le projet couvre un large éventail d'opérations mathématiques, notamment l'arithmétique élément par élément, l'agrégation de données basée sur les axes et les calculs de produit scalaire. Elle inclut également des utilitaires complets pour la manipulation de tableaux tels que le remodelage, l'aplatissement, l'empilement et la génération de grilles de coordonnées, ainsi qu'une prise en charge de la génération de tableaux aléatoires et de la sérialisation.
