matrices
- 1Plural of matrix.
The graphics software multiplies large matrices to rotate the 3D model on screen.

Note
The plural changes its ending rather than adding -s: -ix becomes -ices, as appendix gives appendices and vertex gives vertices. Every meaning of the singular takes it, from the grids of numbers an algebra class multiplies to molds for casting and the tissue in which cells are embedded. The same spelling also serves as the plural of the noun matrice.
- 2Plural of matrice.
Note
Matrice is an obsolete spelling of matrix, and in rare archaic writing it also named the womb. Its plural belongs to older texts, where a reader should keep both possibilities open: the old spelling of matrix, or wombs. Anything written today means the plural of matrix.
