Web23 sep. 2024 · Matrices: A matrix is a 2D array of numbers, so each element is identified by two subscripts instead of just one. We usually give matrices uppercase variable names with bold characters, such as A. We usually identify the elements of a matrix by using its name in italics but not in bold, and the subscripts are listed with separating commas.
