1. Matrix (mathematics) - Wikipedia
Description: is a matrix with two rows and three columns. This is often referred to as a "two by three matrix", a "2×3-matrix", or a matrix of dimension 2×3.Without further specifications, matrices represent linear maps, and allow explicit computations in linear algebra.Therefore, the study of matrices is a large part of linear algebra, and most properties and operations of abstract linear algebra can …
