It is denoted by I.Įqual Matrix: If two matrices are said to be equal if they are same order if their corresponding elements are equal to the square matrix. Unity or Identity Matrix: If a square matrix has all elements 0 and each diagonal element is non-zero, it is called an identity matrix. In a matrix all the elements are zero then it is called a Zero Matrix or Null Matrix and it is generally denoted by 0. Null Matrix: Null Matrix is also called Zero Matrix. Thus the value of the column matrix will be 1. Just like row matrices had only one row, column matrices have only one column. It has only one column and the order of a matrix will be m x 1. A= mxn is a column matrix, if n=1 then column matrix is represented as A= mx1 . For example, A= is row matrix of order 1 x 4.Ĭolumn Matrix: A Matrix having only one column is called a Column Matrix. It has only one row and the order of a matrix will be 1 x n. A= mxn is a row matrix, if m=1 then row matrix is represented as A= 1xn . Row Matrix: A Matrix having only one row is called a Row Matrix. Now, using different conditions, the various matrix types are categorized along with their definition. There are different types of matrices, basically categorized on the basis of the value of their elements, their order, number of rows and number of columns, etc. For example, we have a 3 x 2 matrix, the number of rows is equal to 3, and the number of columns is equal to 2. The size of the matrix is written as m x n, where m is the number of rows and n is the number of columns. Therefore the order of the matrix is equal to m x n, and it is also called as ‘m by n’. The number of rows is represented by ‘m’ and the number of columns is represented by ‘n’. The order of the matrix is defined as the number of rows and columns. Order a Matrix – Definitionīasically, a two-dimensional matrix consists of the number of rows and the number of columns. The entries are the numbers in the matrix and each number is known as an element. A Matrix is a rectangular array of numbers or symbols which are generally arranged in rows and columns. It is a rectangular array and two- dimensional. Matrices are defined as a rectangular array of numbers or functions. Before we learn about the Order of a Matrix let us know What is a Matrix.
