MAYTR-iks/ˈmeɪtrɪks/

A matrix is a grid of numbers or cells, or the environment something develops in: a risk matrix; a data matrix. Grid is everyday; table is looser. Complete the risk matrix before the trip. Mix-up: mattress is a bed; metre is a unit (already in the dictionary). Do not write matrix for a simple two-row table without cells.

Meaning

A grid of numbers or cells; also the environment in which something develops.

Examples

• “Complete the risk matrix before the trip, H&S said.”
• “A 2×2 matrix featured in the maths paper, which is the array sense.”

Good to know
