Matricielles

Matricielles is a term that appears in some mathematical vocabularies as the plural form of an adjective or noun related to matrices. It is not established as an English term; in English one would normally say matrices for the objects and matricial or matrix-related for the adjectives. The stem comes from matrix (from Latin matrix) via French matrice or Italian matrice, with feminine/masculine adjectival forms such as matriciel, matricielle, or matriciale in various languages. In contexts where it occurs, matricielles functions as a descriptor of concepts involving matrices or as a plural noun referring to multiple matrix objects.

In typical usage, matricielles would refer to matrix-related concepts, objects, or formulas. For example, phrases like formules matricielles (matrix formulas), produit matriciel (matrix product), or propriétés matricielles d'une transformation linéaire (matrix properties of a linear transformation) illustrate how the term can appear in multilingual texts to denote matrix-based relations, operations, or characteristics.

The term is not standard in English mathematical writing, and its meaning is highly dependent on context. When writing for an English-speaking audience, it is generally clearer to use matrices for the objects and to employ adjectives such as matricial or matrix-related to describe properties or operations. For multilingual readers, matricielles may be encountered in translations or regional textbooks, where adherence to the target language’s conventional terms is preferred.
