and matrices are also represented as rows and columns, we can represent matrices as 2 dimensional arrays while programming. Consider the 3x3 matrix below: 2 9 4 0 7 8 3 5 1 It’s equivalent 2d array representation will be: @adoranwodo REPRESENTING MATRICES REAL LIFE USES OF ARRAYS var matrix = new int[3, 3] { // Row 0 { 2 , 9, 4 }, // Row 1 { 0 , 7, 8 }, // Row 2 { 3 , 5, 1 }, }
