X–Y–Z matrix

In mathematics, an X–Y–Z matrix is a generalization of the concept of matrix to three dimensions.

An X–Y–Z matrix $A$ will thus have components $A_{i, j, k}$ where

$1\le i\le M, \ 1\le j \le N, \ 1\le k \le P$

for some positive integers $M, N, P.$

Such matrices are helpful for example when considering grids in three dimensions, as in computer simulations of three-dimensional problems.
