A matrix consists of a set of numbers arranged in rows and columns enclosed in brackets.
We usually denote a matrix by a capital letter.
C is a matrix of order 2 × 4 (read as ‘2 by 4’)
Each number in the array is called an entry or an element of the matrix. When we need to read out the elements of an array, we read it out row by row.
Each element is defined by its position in the matrix.
In a matrix A, an element in row i and column j is represented by aij
a11 (read as ‘a one one ’)= 2 (first row, first column)
a12 (read as ‘a one two') = 4 (first row, second column)
a13 = 5, a21 = 7, a22 = 8, a23 = 9
