Matrix Types: Overview. The different types of matrices are given below: Types of Matrices: Explanations. Row Matrix. A matrix having only one row is called a row …Matrices. A matrix is a rectangular array of numbers that is usually named by a capital letter: A, B, C, and so on. Each entry in a matrix is referred to as a i j , such that i represents the row and j represents the column. Matrices are often referred to by their dimensions: m × n indicating m rows and n columns.D = A – B = aij – bij. Thus, the two matrices whose difference is calculated have the same number of rows and columns. The subtraction of the two matrices can also be defined as addition of A and -B (negative of matrix B), since the process of addition is similar to subtraction. A – B = A + (-B)Matrices, being the organization of data into columns and rows, can have many applications in representing demographic data, in computer and scientific applications, among others.
