How to say "matrix" in Japanese

Choosing the right word

マトリックスCommon
nounThe katakana loanword, covering senses of 'matrix' outside mathematics: a grid-like arrangement for organizing or cross-referencing data, or a surrounding substance in scientific contexts; in mathematics itself, 行列 is the usual term.
行列ぎょうれつJLPT N2approx.Common
nounThe usual mathematical term for a matrix, a rectangular array of numbers. Outside mathematics 行列 ordinarily means a line or queue of people, so it is not the word for other 'matrix' senses.

Use 行列 for the mathematical matrix of rows and columns; 「マトリックス」, the loanword, covers other senses such as a grid for organizing data or a surrounding substance.
