Abstract
Matrices are arrays of numbers. The arrays have a dimension of n × m. The present discussion is limited to two cases: square arrays (n x n) that are called matrices, and vectors (1 × n). The matrices have elements a ij where the indices i (1 ≤ i ≤ n) denote the rows while; (1 ≤ j ≤ n) denote the columns.
